Decoding the designation

P2B — two-bolt pillow block. The shaft runs parallel to the mounting surface and the unit bolts down through a slotted base.

GT — Grip-Tight. A tapered concentric adapter draws up inside the bearing bore and clamps the shaft evenly all the way round, which centres the inner ring and holds against rotation in both directions.

H — the heavy-section Grip-Tight housing, which puts more iron around the bore and the bolt bosses than the standard GT block.

10 — Grip-Tight adapter size 10, running a 210-series ball bearing.

Housing style and bolt pattern

Housing Style: Two-bolt pillow block, cast iron, slotted base. Bolt Center To Center Length: 6.38 in to 7.44 in — the base is slotted, so the unit accepts a range of existing hole patterns rather than one fixed spacing. Base to bore centreline: 2-1/2 in. Overall length: 8.88 in. Overall height: 4.96 in.

What these specs mean in practice

Dynamic Load Rating: 7,891 lb. Static Load Rating: 5,213 lb. Insert Series: 210. Locking Method: Grip-Tight concentric adapter. Expansion Type: Non-expansion.

A Grip-Tight adapter grips a plain commercial shaft over its full circumference and pulls the inner ring true, so the unit runs concentrically and holds in either direction of rotation. That is what separates it from a setscrew or eccentric collar mount, both of which pull the ring slightly off centre and prefer one direction. It also releases cleanly off a shaft that has been running for years. As the non-expansion build, this housing holds the outer ring axially, so it is the unit that sets the shaft position on a two-bearing line while the expansion unit at the other end absorbs thermal growth.

Quantity and configuration

Unit Quantity: 1 Pc. Cast iron housing and 210-series ball bearing, assembled. The Grip-Tight adapter sleeve that completes the shaft mounting is a separate Dodge part, selected to the shaft size in hand.

Interchange guidance

MPN Variants: P2B-GTH-10, P2BGTH10, P2B GTH 10. The P2B-GTH-10-E is the same housing and the same 210-series bearing in the expansion build, Dodge stock number 130700, and the two are commonly fitted as a pair at opposite ends of one shaft. Dodge runs the same GTH housing family at other adapter sizes, so the 12 size steps up to a 212-series bearing. Bore-coded Grip-Tight units such as the P2B-GTH-207 carry a shaft size in the designation instead of an adapter size.
