Value Collection 30870 Shaft Clamp Collar 2.375 Bore Steel

Product Description

The VALUE COLLECTION 30870 is a steel shaft clamp collar used to secure, locate, or limit the axial movement of shafts in rotating mechanical assemblies. Clamp collars grip the shaft by clamping force rather than a set screw bearing directly on the shaft surface, which reduces shaft marring and allows for more precise positioning. This collar is constructed from steel for durability in industrial and mechanical drive applications. The package includes 5 collars, making it a practical quantity for maintenance shops and assembly operations that require multiple collar placements on a single machine or across several units.

Shaft clamp collars like the 30870 are used across a wide range of mechanical and industrial applications, including HVAC drive assemblies, pump and motor shaft positioning, conveyor systems, and general power transmission setups. They are typically installed by millwrights, maintenance technicians, and mechanical contractors working on rotating equipment. The steel construction holds up well in moderate-duty environments where corrosion exposure is limited.

Key Features

• Steel construction provides strength and durability in mechanical drive applications
• Clamp-style collar design reduces direct shaft surface damage compared to set screw collars
• 2.375 inch bore diameter for shaft fitment
• Package quantity of 5 collars for multi-point installations or stocking needs
• Compact form factor suitable for space-restricted shaft assemblies

Compatibility

Designed as an OEM-style replacement or service collar for general mechanical shaft assemblies requiring a 2.375 inch bore clamp collar in steel construction.

Installation Notes

Shaft clamp collars are installed by mechanical technicians and maintenance personnel. Always de-energize and lock out the drive system before working on any rotating shaft assembly, following LOTO (lockout/tagout) procedures per OSHA 1910.147. Position the collar at the desired axial location on the shaft before tightening the clamp fastener evenly to ensure uniform grip. Avoid over-tightening, which can deform the collar or damage the shaft surface.
