Modern Linear Guide Rollers are available in 5 sizes and a variety of materials, off the shelf. The Inner and outer races of the rollers are made from either 52100 bearing steel or 440 stainless steel. The 52100 version can have nitrile rubber seals (a rubber coated metal washer) that fit in grooves in the inner and outer race, or a metal shield that is pressed into the outer race with a slight gap at the inner race.
The seal would be favored in applications where there is moisture or fine particulates. The shield is good for general purpose applications. 440 stainless steel rollers are only available with seals. All standard rollers include nylon ball retainers and are pre-lubricated with NLGI #2 grease. Guide rollers are designed to run on Modern Linear Single or Double Edge Track. Mounting of the rollers is facilitated with our stationary and adjustable bushings, but can also use standard bolts and washers. Rollers for special applications such as vacuum or cleanroom can be requested by contacting the factory. Specials can include changes to any component or grease specification.
