Application overview
How NSK bearings are specified for Conveyors & Material Handling
The right NSK bearing for this application is defined by its full part number, its position in the assembly and its exact execution, not by bore and outside diameter alone. Feed Mechanisms Company supplies genuine NSK bearings matched to that complete specification.
Belt conveyors, bucket elevators and handling lines use mounted pillow block units on pulley and idler shafts, plus self-aligning bearings where long shafts flex. Dust, washdown and misalignment between supports are everyday conditions. Maintenance buyers need units that fit the existing housing bolt pattern and handle contamination at each position.
- Match the insert bearing and housing designation together (such as UC with P, F or T housings) so replacements drop into the existing mounting.
- Choose units with seals and relubrication provisions for dusty or washdown areas, or stainless versions where corrosion is a concern.
- Use spherical roller or self-aligning ball bearings on adapter sleeves for long pulley shafts, and list the sleeve and housing references.
- Record locating and non-locating bearing positions on each shaft so the shaft can expand without overloading the bearings.
