This SKF unit arrives preassembled: a Y-series insert bearing seated in a pillow block housing. It supports rotating shafts where installation needs to be straightforward and the bearing must stay protected from dust and moisture. You will find it on conveyors, fans, mixers, and agricultural equipment. MR Industrial Accessories supplies this line and helps you match the right size to your shaft.
The letters TUJ denote a Y-bearing pillow block housing with an insert bearing, featuring a base and mounting holes. The digits that follow show the assembly size: larger numbers mean a bigger shaft and wider overall footprint. For example, TUJ 507 and TUJ 508 are smaller than TUJ 509, TUJ 510, and TUJ 512. Suffixes may indicate sealing or locking variations, so confirm each part number with MR.
Typical applications include belt conveyors, bucket elevators, mixers, fans, screens, and processing equipment in food, chemical, and agricultural plants. The pillow block shape mounts on steel or concrete with two bolts, which keeps initial alignment simple and speeds up replacement during maintenance. In dusty or wet areas, consider additional sealing protection.
When selecting a housing, confirm the shaft diameter and how the insert bearing locks: some use set screws, others a taper bushing. Check the sealing arrangement as well. During mounting, set the base on a flat surface and tighten bolts gradually to prevent housing distortion. Factory grease usually suffices, but continuous duty may call for periodic replenishment based on your schedule.
SKF Y-bearing housings with insert bearings interchange with other brands that share the same standard dimensions. Before replacing, compare shaft diameter, hole spacing, and center height. If the original equipment lists a specific part number, keeping that designation helps ensure fit. MR can suggest equivalents without requiring machine modifications.
If you have the housing part number, send it via WhatsApp or email to MR Industrial Accessories for a quote. Without the number, a photo or measurements of the shaft and base help us identify it. We supply SKF.
