The SEALMASTER VTBB 200 is a mounted pillow block that comes with its insert bearing already fitted into the housing. This factory assembly keeps the outer ring concentric with the housing and reduces installation work on site. The unit provides fixed support for rotating shafts and includes self-aligning capability, making it a practical choice for power transmission equipment where some misalignment is possible.
The VTBB 200 series covers pillow blocks with insert bearings. In part numbers such as VTBB-220S and VTBB-232S, the digits after the hyphen give the nominal shaft size: 220 for 20 mm and 232 for 32 mm. The letter S shows that the insert has reinforced sealing, which helps hold lubricant in and keep dust and moisture out. Ordering by the full part number is the simplest way to get the right fit for your shaft.
These units are common in belt conveyors, bucket elevators, mixers, mills and process equipment across food, chemical and aggregate plants. You will also find them in woodworking, textile and bottling machinery. The housing mounts to a frame with two bolts, and the self-aligning insert absorbs small shaft misalignments. That reduces vibration and helps the assembly last longer.
When selecting, check the shaft diameter and the load type. In power transmission, the load is mainly radial. The S sealing is a good choice where dust, water or frequent washdowns are present. During mounting, set the base on a flat, rigid surface, tighten the mounting bolts and confirm the shaft turns freely. The insert is lubricated at the factory; in service, follow your maintenance plan with a compatible grease. Proper alignment avoids unwanted axial loads.
SEALMASTER VTBB 200 pillow blocks can replace mounted bearings from other brands with matching dimensions, such as SKF, FAG, NTN or Timken, as long as shaft diameter, center height and mounting hole spacing are the same. For a quote, send the complete part number and, if you have them, the main dimensions. MR Industrial Accessories can help you find a compatible alternative or the special manufacturing you need.
