SXR — Dodge eccentric collar ball bearing, wide inner ring, normal duty. The wide inner ring gives the collar a long seat on the shaft. 100 — Dodge bore code, read as whole inches and sixteenths: 1-00/16 = 1 in shaft. 131805 — Dodge stock number for this build, the number distributors order against. Housing style and bolt pattern: Housing Style: Two-bolt pillow block, cast iron. Bolt Center To Center Length: 3.69 in to 4.5 in — the base is slotted, so the unit accepts a range of existing hole patterns rather than one fixed spacing. Base to bore centreline: 1.44 in. Overall length: 5-1/2 in. Overall height: 2.77 in. What these specs mean in practice: Bore / Shaft Size: 1 in. Locking Method: Eccentric collar — the collar is bored off centre, so driving it round against the extended inner ring wedges the two together and grips the shaft over the full circumference. It seats and releases faster than a setscrew mount and holds firmly in the direction of rotation, which suits conveyor and fan drives that always turn the same way. Expansion Type: Non-expansion. This position holds the shaft axially, so the opposite bearing takes up thermal growth. Closure Type: Single-lip contact seal, which keeps grease in and plant dust out at general industrial speeds. Duty rating: normal duty, wide inner ring. Quantity and configuration: Unit Quantity: 1 Pc. One complete pillow block, cast iron housing, insert and eccentric collar assembled, per unit. Mounting data: Bore / Shaft Size: 1 in. Bolt Center To Center Length: 3.69 in to 4.5 in, slotted. Base to bore centreline: 1.44 in. Overall length: 5-1/2 in. Overall height: 2.77 in. Interchange guidance: MPN Variants: P2B-SXR-100, P2BSXR100, P2B SXR 100, 131805. The P2B-SXR-100-HT is the same unit built for elevated temperature service, Dodge stock number 056842. The P2B-SC-100 is the same two-bolt pillow block footprint at the same 1 in shaft on a setscrew-locking insert, so the two are a footprint match on different locking methods. Dodge codes shaft size in whole inches plus sixteenths across the SXR range, so 106 is 1-3/8 in and 200 is 2 in on the same series.
