Value Collection 30872 Two Piece Shaft Collar 7/8 in Steel 5pk

Product Description

The VALUE COLLECTION 30872 is a two-piece shaft collar designed for shaft positioning, spacing, and retention in mechanical drive assemblies. Machined from steel with a black oxide finish, it features a 7/8 inch outside diameter and a 3/8 inch width. The two-piece construction allows the collar to be installed or removed anywhere along a shaft without disassembling adjacent components, making it a practical choice for maintenance-heavy applications. Each package contains 5 collars. This collar suits industrial, agricultural, and HVAC blower-shaft applications where reliable axial control is required.

Two-piece shaft collars are commonly used in conveyor systems, pump assemblies, blower shafts, and general power transmission setups. The 0.375 inch bore diameter accommodates standard fractional shafting. The black oxide finish provides a base level of corrosion resistance suitable for indoor and light-duty environments. Machinists, millwrights, and mechanical service technicians typically specify this style when repeated collar adjustment or repositioning is anticipated during the equipment lifecycle.

Key Features

• Two-piece design allows mid-shaft installation and removal without full disassembly
• 7/8 inch outside diameter and 3/8 inch width for compact axial footprint
• 0.375 inch bore diameter fits standard fractional shafting
• Steel construction with black oxide finish for durability and corrosion resistance
• Pack of 5 collars per package

Compatibility

Designed as an OEM-style replacement or upgrade collar for mechanical drive assemblies using standard 0.375 inch fractional shafting.

Installation Notes

Installation is performed by millwrights or mechanical technicians during equipment assembly or service. De-energize and lock out the drive system before installing or adjusting shaft collars. Two-piece collars are secured by tightening the fastener hardware evenly on both halves. Do not overtighten fasteners beyond the hardware manufacturer specifications, and verify axial position with a dial indicator where precise placement is required.
