RHPSFT1-9/16Two-Bolt Oval Flange Unit – 1-9/16 in Bore, Cast Iron, Set-Screw Locking

Product Description

What this part is

RHP Self-Lube SFT1-9/16 mounted ball bearing flange unit. Housing Style: Two-Bolt Oval Flange, cast iron, one piece. Bolt Count: 2. Bore / Shaft Size: 1-9/16 in (39.6875 mm). Design Units: Inch. Locking Method: Two knurled cup-point set screws in the extended inner ring. Series: SFT, normal duty. Housing Material: Cast Iron. Unit Quantity: 1 Pc.

Housing style and bolt pattern

Oval flange body with two mounting holes on the long axis, either side of the bearing bore. The flange face bolts to a vertical or angled plate and locates the shaft through the plate, so the unit carries the shaft perpendicular to the mounting surface rather than parallel to it as a pillow block does. Series SFT covers bores from 12 to 60 mm and 1/2 to 2-7/16 in.

Insert bearing data

Insert Series: RHP 1000G. Rolling Elements: Balls. Cage Type: Two-piece riveted metal cage. Cage Material: Pressed Steel. Seal Type: Single lip seal, nitrile rubber moulded lip bonded to a steel pressing secured in the outer ring. Insert Outer Ring: Spherical seating. Inner and outer rings are through-hardened high quality steel with super-finished raceways.

What these specs mean in practice

Operating Temperature Range: −20 to +110 °C on the standard mineral oil / lithium soap grease. The spherical outer seating lets the insert swivel in the housing, so the unit takes up initial shaft misalignment on mounting — useful on a flange unit, where the plate flatness sets the shaft angle. Set screw locking suits general drive duty; eccentric collar and taper sleeve executions of the same housing cover vibration and shock load.

Relubrication

Relubrication: Grease nipple fitted to the housing as standard. Grease passes through the housing fitting into the insert outer ring. Lubricant: grease.

Identification and interchange

Part Number: SFT1-9/16. MPN Variants: SFT1-9/16, SFT 1-9/16, SFT-1-9/16, SFT1.9/16, SFT1 9/16. Series: SFT. Country of Origin: United Kingdom. The insert lifts out of the housing for replacement, so the housing and the insert are separately orderable items within the Self-Lube range. The four-bolt square-flange counterpart on the same insert is the SF series.
