and Bushings Products and Supply
Miniature bearings designed and available to handle
radial, thrust and combined loads in proportion to the capacity requirements of
the small shafts for which they are designed. They are commonly used in
fractional horsepower motors, domestic appliances, precision instruments, tape
recorders and similar devices. Miniature bearings include all of the various
combinations of shields and seals available in larger series bearings. Miniature
bearings are available in low and standard bearing quality, chromium-alloy, high
carbon steel and stainless steel.
Miniature bearings are available for pulley, guide roller and
pinch roll by several manufacturers in several bore sizes providing the
advantages of light weight, low inertia, low torque, and accurate running
characteristics with minimal runout and wobble.
Many Miniature bearings units feature outer ring assemblies with
integral molded tires. The most commonly used tire materials are aluminum,
steel, and a variety of engineered plastics such as nylon, polycarbonate, acetal
resin, or polyurethane. The tire material and configuration are determined by
the particular application requirements. Standard materials and shapes can be
made available in many sizes.
