Small two-piece stainless steel clamp collar with two socket-head screws

Ruland Manufacturing

Ruland Manufacturing SP-2-SS 2-Piece Clamp Shaft Collar 1/8 in 303 Stainless Steel

SKU CH-FH2M-KG887

Two-piece clamp shaft collar with 1/8 in bore and 5/8 in outside diameter, made from 303 stainless steel for corrosion resistance

  • Two-piece design allows installation without shaft removal
  • 303 stainless steel construction resists corrosion in harsh environments
  • 1/8 inch bore fits small-diameter precision shafts
  • .77 inch clearance diameter provides generous assembly space
  • 9/32 inch collar width delivers compact axial footprint

Precision shaft collar for light-duty assemblies

The Ruland Manufacturing SP-2-SS is a two-piece clamp collar machined from 303 stainless steel. It fits a round bore of 1/8 inch and secures components on shafts without marring the surface. Maintenance teams and prototype builders choose it when quick repositioning is required.

Consistent clamping under continuous vibration

The two-piece design distributes holding force evenly around the shaft, resisting loosening during sustained vibration better than single-split alternatives. Stainless screws maintain torque without galling, so the collar stays fixed through extended duty cycles in conveyors, test rigs or adjustment mechanisms.

Low thermal impact and clean operation

303 stainless steel resists corrosion and does not require lubrication, eliminating oil mist or particulate contamination in sensitive environments. The material handles ambient temperature swings without dimensional change, and the smooth bore finish prevents fretting wear during normal rotational or axial loading.

Questions about this item

How much clearance does the 0.77 in diameter add around the 1/8 in shaft when the collar runs continuously?

The 0.77 in clearance diameter provides a fixed radial gap around the 1/8 in bore; no heat, noise or power draw is generated because the collar is a passive mechanical clamp.

Which fastener must I supply to secure the 2-piece 303 stainless steel clamp on a 1/8 in shaft?

The collar includes its own stainless steel screw; no separate fastener is required for installation.

Will the 5/8 in outside diameter and 9/32 in width interfere with adjacent components on a legacy inch-series shaft?

The 5/8 in OD and 9/32 in width match standard inch-series dimensions, so the collar fits existing setups without modification.
