Bearings • Roller Bearings

Roller bearings is a type of rolling element bearing. They use cylinders that are greater in length than the diameter. Relative to ball bearings, roller bearings have higher radial load capacity. They have low axial load capacity and higher friction. Also in comparison to ball bearings, the bearing capacity of roller bearings can decrease at a faster rate if the inner and outer races are not aligned properly. Common types of roller bearings include cylindrical, spherical, tapered, and needle. They are ideal for heavy-duty and moderate-speed functions. But cylindrical bearings have lower speed capabilities.

  • QM Bearings & Power Transmission

    QM are manufacturers of Blue Brute mounted roller bearings that come in most inch and metric sizes, are built to order, made of rugged steel  housings, have external covers for extra sealing protection, and are easily converted from fixed to floating in the field. These roller bearings dimensionally interchange with virtually all other mounted  units. QM's V-Lock Series utilizes mechanical withdrawal on double nut units for easy removal.
