The VTBS is a mounted bearing unit that arrives pre-assembled and aligned from the factory, pairing a cast housing with an insert bearing. It supports rotating shafts on frames, beds and structural bases where secure fixing and straightforward installation matter. SEALMASTER is one of the bearing brands we supply.

The VTBS code covers a family of pillow blocks with insert bearings. The number that follows — 20, 25, 30, 35, 40, 45 or 50 — steps through the size range from smallest to largest, while the MM suffix marks the unit variant. VTBS-20 MM and VTBS-50 MM sit at opposite ends of the same line: identical mounting principle, different shaft capacities. For an accurate inquiry, the complete code is the key detail to provide.

Typical installations include belt and chain conveyors, mixers, bucket elevators, blowers, packaging lines and aggregate processing equipment. In food, chemical and cement operations, these units handle shafts turning at moderate speeds under radial load with some axial load. They also appear in agricultural machinery and material handling equipment exposed to dust or ambient humidity.

Selection begins with shaft diameter and the radial and axial loads the unit will see. Confirm the base sits flat on the structure and that mounting tolerances do not distort the housing. The insert seal determines performance against dust, water or washdowns, so match protection to the environment. Replenish lubrication according to the duty cycle, and check shaft alignment to avoid side-loading the insert.

Mounted pillow blocks are interchangeable across brands by series number and shaft diameter, though housing, sealing and fastening details differ between manufacturers. Before replacing a unit, compare shaft diameter, center height and base hole spacing. When space is tight, those dimensions — not just the commercial code — define the compatible alternative.

To replace a VTBS pillow block or add units to existing equipment, send the full code via WhatsApp or email. With the reference and shaft diameter, we will quote the unit and, if needed, point to a compatible alternative for your mounting. Custom split plummer block housings are also manufactured for special cases.
