Product Description

What this part is:

Dodge P2B-GTH-10-E mounted ball bearing pillow block, Dodge part number 130700. Bearing type: Mounted ball bearing, two-bolt pillow block. Housing Style: Two-bolt pillow block, cast iron. Locking Method: Grip-Tight concentric adapter mount. Expansion Type: Expansion (float). Insert Series: 210. Adapter size: 10. Duty rating: normal duty. Rolling Elements: Balls. Number Of Rows: 1.

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.

E — expansion. The outer ring is free to slide axially in the housing bore, so this position takes up shaft growth while the opposite bearing sets the axial location.

130700 — Dodge stock number for this build.

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.

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. A setscrew or eccentric collar mount pulls the ring slightly off centre and prefers one direction. Expansion Type: Expansion (float).

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.

Mounting data:

Bolt Center To Center Length: 6.38 in to 7.44 in, slotted. Base to bore centreline: 2-1/2 in. Overall length: 8.88 in. Overall height: 4.96 in. Material: Cast iron housing, chrome steel bearing.

Interchange guidance:

MPN Variants: P2B-GTH-10-E, P2B-GTH-10E, P2BGTH10E, P2B GTH 10 E, 130700. The P2B-GTH-10 is the same housing and the same 210-series bearing in the fixed, non-expansion build. Dodge runs the same GTH housing family at other adapter sizes, so the P2B-GTH-12-E is the 212-series unit one size up, Dodge stock number 130702. Bore-coded Grip-Tight units such as the P2B-GTH-207-E carry a shaft size in the designation instead of an adapter size.
