Dodge P2B-SC-203, Dodge item number 123820, is a two-bolt pillow block ball bearing unit. Bearing Type: Mounted single-row ball bearing insert in a pillow block housing. Housing Style: Two-bolt pillow block, cast iron, standard duty. Bore / Shaft Size: 2-3/16 in (55.56 mm). Series: 211 wide inner ring. Locking Method: Setscrew. Closure Type: Contact lip seals. Expansion Type: Non-expansion. Dynamic Load Rating: 9,755 lbf. Static Load Rating: 6,588 lbf. Limiting Speed: 2,500 rpm. GTIN: 782475113989.
P2B — two-bolt pillow block housing, bolted down to a horizontal base with the shaft running parallel to that surface.
SC — setscrew locking on a standard-duty cast iron housing, the general-purpose Dodge mounted ball bearing line.
203 — bore code for a 2-3/16 in shaft.
Locking Method: Setscrew. The setscrews bite the shaft through the extended inner ring, holding the insert against rotation and axial creep, and they release again with a hex key when the unit is changed out. The insert’s spherical outside diameter seats in a matching spherical housing bore, so the unit takes up initial shaft misalignment on a frame that is not perfectly machined. Dynamic Load Rating: 9,755 lbf and Static Load Rating: 6,588 lbf are the 211-series ratings. Limiting Speed: 2,500 rpm.
Housing Style: Two-bolt pillow block, cast iron. Bolt Center To Center Length: 6.38 to 7.44 in, on slotted feet that allow the block to be shifted along the base for alignment. Base to shaft centreline height: 2.5 in.
Expansion Type: Non-expansion — this position holds the shaft axially, so a floating unit belongs at the far end of a long shaft that grows with temperature. Relubrication: grease fitting in the housing. Closure Type: contact lip seals on both faces of the insert.
Unit Quantity: 1 Pc. Complete pillow block — cast iron housing with the 211-series ball insert and its setscrew collar fitted.
Part Number: P2B-SC-203. Base Number: 123820. Searchable variants: P2BSC203, P2B SC 203, P2B-SC203. The matching insert on its own is the Dodge INS-SC-203. GTIN: 782475113989.
