Frequently asked questions

What does MUCTBL205-14B mean?

MUCTBL205-14B is an AMI inch PBT thermoplastic 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, TBL = housing style: PBT thermoplastic tapped base pillow block. Housing part number is TBL205, 205 = frame size 205, 200 series (normal duty), -14 = bore in sixteenths of an inch: 14/16" = 7/8" (22.22 mm), B = housing color: black.

What is the bore size of MUCTBL205-14B?

The bore of MUCTBL205-14B is 7/8" (22.22 mm).

The housing of pillow block bearing, crafted from plastic, is engineered to withstand moisture-rich and chemically aggressive conditions with the lightweight corrosion resistance and rust-free durability 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 Plastic for the bearing housing?

Because this pillow block bearing is specifically designed for moist, corrosive, or chemically aggressive conditions, plastic delivers lightweight corrosion resistance and zero rust where standard metal housings are prone to oxidation and surface degradation, 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.
