A VTBS unit is a pillow block assembly made up of a rigid housing plus a VTBS 200 series insert bearing. It carries rotating shafts in equipment that calls for a compact, self-aligning support that goes on without complications. MR Industrial Accessories LLC supplies the SEALMASTER line to plants across the United States, Canada, Mexico and South America, and helps buyers match the right configuration to their shaft, load and operating conditions.

Read the reference in two parts. VTBS identifies the housing family built around an insert bearing, and the number that follows pins down the size — VTBS-220S and VTBS-232S are examples. The trailing S points to a particular seal that keeps contaminants out of the bearing. Sizes in the VTBS 200 series are standardized, and each part number ties together housing type, shaft size and sealing. The safest way to decode a specific reference is to work from the manufacturer's dimension table, or to send us the full part number.

Typical installations include belt conveyors, bucket elevators, mixers, mills, screens and other process equipment in food, chemical and aggregate plants, along with industrial fans, centrifugal pumps and agricultural machinery. The pillow block format simplifies bolting to steel structures or concrete bases and makes shaft alignment during installation reasonably straightforward. Users value the support for its resistance to outdoor conditions.

Sizing starts with three inputs: shaft diameter, the radial and axial loads involved, and where the unit will operate. The S seal handles dust and moisture, though frequent washdowns or chemical exposure may justify extra sealing or a different material. Insert bearings normally arrive prelubricated; high-temperature or high-speed duty calls for a check on the correct lubricant. Getting the housings aligned with each other matters, since misalignment introduces parasitic loads. Mount on flat surfaces and tighten the bolts to the manufacturer's recommended torque.

On interchangeability, SEALMASTER VTBS housings can be swapped with comparable mountings from SKF, FAG or NTN, provided the critical dimensions line up: shaft diameter, hole spacing, height to center and mounting type. A similar part number is not proof of fit — compare the dimension drawing. For a replacement, send a photo or the number stamped on the existing housing and we will point you to the compatible option in our catalog.
