Frequently asked questions

What does MUCTB205-14 mean?

MUCTB205-14 is an AMI inch 304 cast stainless steel tapped base pillow block unit with a stainless steel wide inner ring insert and set screw locking, for a 7/8" (22.22 mm) shaft. M = stainless steel insert bearing, UC = wide inner ring ball bearing insert, set screw locking, spherical outer ring. Insert part number is MUC205-14, TB = housing style: 304 cast stainless steel tapped base pillow block. Housing part number is MTB205, 205 = frame size 205, 200 series (normal duty), -14 = bore in sixteenths of an inch: 14/16" = 7/8" (22.22 mm).

What is the bore size of MUCTB205-14?

The bore of MUCTB205-14 is 7/8" (22.22 mm).

The housing of pillow block bearing, crafted from stainless steel, is engineered to withstand washdown, food-grade, and marine conditions with the high corrosion resistance and hygienic structural strength needed to keep the overall mounted bearing assembly performing reliably over the long term.
Shaft retention is achieved through set screw locking in this pillow block bearing unit, which secures the shaft reliably against moderate loads and low-to-medium vibration — provided the shaft is of standard ground finish and the screws are correctly torqued — without damaging the shaft surface.

Why choose Stainless Steel for the bearing housing?

Because this pillow block bearing is specifically designed for washdown, food-grade, or marine conditions, stainless steel delivers high corrosion resistance combined with structural strength where standard carbon steel or cast iron housings are prone to rust and contamination risk, making it a purpose-built choice for this application rather than a generic substitute.

Why does this bearing use Set Screw Locking to secure the shaft?

Set screw locking works by tightening one or two hardened screws directly against the shaft surface, which makes it well suited to applications where shaft positioning is fixed and loads are moderate. Its main advantage over other shaft locking methods is simplicity and low cost, which matters most when quick installation and minimal tooling are the priority.
