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, the number distributors order against. 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. 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. Expansion Type: Expansion (float) — pair this housing with a fixed unit at the other end of the shaft, and the two together carry a long shaft through its temperature range without loading the bearings axially. 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.
