Supporting the World’s Leading Injection Molding Technologies

Injection molding machines are used to manufacture structural foam products from precision to large parts.  Japanese injection molding machines enjoy a worldwide reputation for their precision and have gained a 40% market share of the international market.  Traditionally, injection molding machines were mainly of the hydraulic type but in light of recent concerns for the environment the motorized type is increasingly popular as they are cleaner and quieter.  Belts are used in the motorized type for injecting and clamping parts.  For these applications Mitsuboshi Belting has chosen to use a special hard rubber that has high strength and durability and generates a transmission volume that is twice as large as the conventional S8M and S14M.  Mitsuboshi Belting also achieved higher transmission efficiency and lower noise with its products, receiving high acclaim from many of the injection molding machine manufacturers.

….. why not talk about belts?

Where can I start.  Why not talk about types .. that sounds like a good place to start.

The above information was found on one of our MBL/Mitsuboshi flyers.  We are proud to be a supplier for MBL/Mitsuboshi and will be respectfully offering this line on our storefront.

Help — I’ve fallen and can’t get up. 

Now that I’ve used the allotment of cliches where do I go from here.  Even the best of us run into brain blocks, and I’m no exception.  I have been doing research, and working hard learning the background information for the new website, www.bearingsinc.net that is soon to be launched.  I know “you’ve heard this all before”, but be assured that it is close to launch date, and it will change consistently once it is launched.  We want to make it better and easier for you to use. 

Right now, I have uploaded “most” of our Timken line; which is our biggest line.  This consists of both ball and roller bearings.  Ball bearings consisting of Angular contact, Wide inner ring, and Housed units. Roller bearings consisting of the Tapered Roller Bearings Cups, cones, and sets that Timken has always been famous for. 

I have also uploaded our Koyo Ball bearing line, which could offer some of the same parts as Timken.  We also have SKF-Chicago Rawhide currently uploaded which offers seals, and speedi sleeves.

In my plans, and my next uploading attempts consist of Koyo NEEDLE bearing line, and MBL (Mitsuboshi) belts.  These will cover quite a bit of items we can currently offer, but you need to watch the sight because once it’s launched, I will be configuring other databases to upload.  This way it will keep the sight changing, and interesting. 

New items = new choices = more options

While I’m not making any promises of a launch date; keep in touch and help us celebrate our launch when all of our hard work has finally come to an end.

3) “Mamaline” Conveyor Belt

The mold and unwanted  bacteria made by food scraps clung to the belt surface are archenemies of the food conveyance.  Mitsuboshi has successfully developed “Mamaline”, which has been made much smoother belt surface than other belts. With “Mamaline”, cleaning the surface of the belts becomes much easier and solves various problems from the aspect of good hygiene.

4) “e-POWER” Loe Edge Belt

“e-POWER”, a belt has been given special notches inside, is superior compared to the usual product in flexibility and energy savings. 

“e-POWER” doesn’t require special profile pulleys. Therefore, it is possible to replace only a belt.  It also helps you to save energy for generators and air-conditioning apparatus.

5) “LOGISTAR” Conveyor Belt

The Conveyor belts used in logistics centers and airports have noise issues when it sideswipes the table that supports them. 

“LOGISTAR” has succeeded in cutting down it’s noise.  Mitsuboshi has made it’s surface smoother by refining it’s structure and reduced it’s noise by 18 decibels compared with their original product.  Mitsuboshi Belts have achieved the silence of a library.

1) Mega Torque GII Timing Belt

Mega Torque G, the timing belt for heavy load equipment, is highly praised in the market.  Mitsuboshi refined it to Mega Torque GII, which makes it possible for the huge machines like injection molding machines or pressing machines to become more compact and to make less noise.  Mega Torque GII has gained 50% larger capacity, reduced noise by 18%and increased the durability by 100%, compared with Mega Torque G, their normal product.

2) Mega Torque EX Timing Belt

Mitsuboshi has developed “Mega Torque EX” for semi conductor producing equipments and machine tools, which require high accuracy  of positioning and advanced following capability.  Mega Torque EX is a highly appreciated timing belt, which it’s high capability is 2 times better than the original Mega Torque G limited torque for teeth jumping.  Mega Torque EX has cut down the oscillatory convergence time by approximately 10% and has improved repetitive positioning accuracy up by about 17%.

Wrapped Wedge Belts, Kraftbands and Pulleys

TB Woods representative, George Riesselmann did a luncheon presentation at Bearings Incorporated on Tuesday, August 31st. 

Lunch consisted of a simple sandwich platter, chips, and deli salads.  Nothing fancy, but gave a much more relaxed atmosphere.  Surprisingly the phones were quiet during this time as well.

This meeting was to promote the QT Power Chain II line.

TB Woods QT Power Chain II belt drive systems are designed for use in a variety of industries including: Lumber Pulp and Paper Packaging Food processing Bottling Aluminum and Steel Petrochemical Sand, Gravel and Concrete Glass

These high performance drive systems are specifically designed for tough applications such as:

• belt conveyors
• de-barkers
• dough mixers
• scrap cutters

Belts Built for Maximum Strength

The result of state of the art design and engineering, the body and teeth of QT Power Chain II belts are made of duRable poyurethane compound specifically blended for uncompromising adhesion to the tensile cords and heavy nylon tooth facing.

The result is a belt that is virtually immune to abrasion and chemical attack.

Heavy duty belts combined with Taper-Lock Sprockets and bushings make QT Powerchain II belt drive systems

– the optimal choice for high-performance in high-torque drive applications.

The QT Power Chain II belt drive system consists of a belt, sprockets, bushings, and other components designed to work together to deliver the best value in power transmission.

Advantages include:

• drive hardware engineered to handle higher horsepower ratings
• drive system design and application engineering assistance

The ORV Vulcanization Process

The ORV (Optibelt Rotary-Vulcanization) process, which was developed by them, differs quite considerably from the traditional methods of vulcanization.  In the ORV process, V-Belts are vulcanized in heated V-Grooves while rotation takes place, hence in the same mode of motion and shape in which they will subsequently give service. 

With the traditional methods of vulcanization it is very difficult to exercise any control over the retention of the nominal lengths of the belts, whereas by means of their electronically controlled cord stabilization process, which they have patented in many countries, the nominal length tolerances of V-Belts vulcanized by the ORV process are restricted to a minimum. 

A “Panzerband”, which revolves around guide rollers and is tensioned by means of a hydraulically operated tension drum, presses the V-Belts into the V-grooves of the heated vulcanizing drum.  The V-Belt flanks and the sides of the pulley grooves, without significant distortion.

Cord Stabilization

Electronically controlled cord stabilization during manufacture gives Optibelt V-Belts their unique SetConstant feature.

Optibelt SetConstant V-Belts of similar nominal length can be assembled into matched sets at random without further measurement.  Length stability is guaranteed over many years, even under adverse storage conditions.
