Decoding the designation

SCHB — screw conveyor hanger bearing. The unit carries the intermediate joint of a screw conveyor from a hanger bracket that straddles the trough, so the bearing sits inside the material stream rather than outside it.

SXR — Dodge eccentric collar ball bearing, wide inner ring, normal duty. The wide inner ring gives the collar a long seat on the coupling shaft.

207 — Dodge bore code, read as whole inches and sixteenths: 2-07/16 = 2-7/16 in shaft.

131335 — Dodge stock number for this build, the number distributors order against.

Housing style and mounting form

Housing Style: Screw conveyor hanger unit. It seats in a Dodge hanger frame that bolts across the conveyor trough, supporting the coupling shaft between two screw sections. That is a different mounting form from a pillow block, which bolts flat to a base, and from a flange unit, which bolts to a vertical face.

What these specs mean in practice

Bore / Shaft Size: 2-7/16 in. Outside Diameter: 5-1/2 in. Overall Width: 2.74 in. Dynamic Load Rating: 11,791 lb. Static Load Rating: 8,100 lb. Limiting Speed: 3,500 rpm. Cage Material: Nylon. Insert Series: 212.

Locking Method: Eccentric clamp collar — the collar is bored off centre, so driving it round against the wide inner ring wedges the two together and grips the coupling shaft around its full circumference. It seats and releases faster than a setscrew mount and holds firmly in the direction of rotation, which is what a screw conveyor asks for since it turns one way under a steady torque. A nylon cage runs quiet and tolerates the shock a conveyor sees when the flight loads unevenly.

Dodge codes shaft size in whole inches plus sixteenths across the SCHB range, so the SCHB-SXR-200 is the 2 in shaft version of this same eccentric collar unit, Dodge stock number 131327.
