Bearing choice follows the duty: load direction, speed, temperature, contamination and how often the position can be serviced. Each page below sets out the typical duty of one industry, the bearing types and suffixes that suit it, and a list of models from our catalogue for that application.
Motor bearings are chosen for low noise, long grease life and the ability to survive shaft voltages from variable-frequency drives. The front
4 bearing choices →Pump and compressor bearings carry a steady radial load from the impeller or rotor, plus whatever axial thrust the hydraulics produce. Two-position
4 bearing choices →Fan and air-handling duty is all about speed, noise and reliability at low load. Belt-driven arrangements dominate, which puts overhung loads on the
4 bearing choices →Wind turbine bearings are specified for a 20-year design life with rotating loads, oscillating duty and no easy access for maintenance. Blade, pitch
4 bearing choices →Mining and quarry equipment is bought on availability, so bearings are specified for shock load, dust and the ability to survive a missed lubrication
4 bearing choices →Rolling mills run bearings under the harshest combination in industry: high load, high temperature, water and scale at the same time. Four-row
4 bearing choices →Machine tool bearings are specified for accuracy rather than capacity. Runout, stiffness and thermal stability set the part quality, so the choice is
4 bearing choices →Robot joints and automation modules are specified for stiffness per unit of envelope, repetition accuracy and a duty cycle measured in millions of
4 bearing choices →Automotive bearings work in high volumes and under cost pressure, with requirements set by the vehicle duty: wheel ends take combined load and shock
4 bearing choices →Conveyor and bulk handling duty is slow, dusty and continuous. Belt pull, material weight and misaligned structures load the bearings steadily, and
4 bearing choices →Start from the duty, not the number. The tables give the type, the reason it suits the application, and the suffix guidance that follows from it - clearance class, seal or shield, cage. The model list is generated from the live catalogue within the bore range that the application usually uses, so the links go straight to specifications and cross-references. If your duty does not match any page, send the application and we will suggest the type, clearance and lubricant.
