Value Collection 30871 Shaft Clamp Collar 5/16 in Bore 5 Pack

Product Description

The VALUE COLLECTION 30871 is a steel shaft clamp collar designed to locate, space, and retain components on rotating or stationary shafts. The 30871 accepts a 0.3125-inch (5/16-inch) bore and is constructed from steel for reliable holding force in mechanical drive applications. Clamp-style collars use a fastener to apply radial clamping force around the shaft, avoiding the shaft damage associated with set-screw designs. This pack includes 5 collars, making it a practical choice for multi-point installations or maintenance stock. Technicians working on conveyor systems, pump assemblies, and light industrial equipment commonly use collars of this type.

These shaft clamp collars are suited for residential and light commercial mechanical assemblies where shaft positioning and component retention are required. Typical applications include motor shafts, fan assemblies, linear guide rods, and pump drive trains. Because the package contains 5 units, installers can address multiple shaft positions in a single order. Steel construction makes these collars appropriate for dry or lightly lubricated environments where moderate load and vibration are present.

Key Features

• Clamp-style design applies even radial force without marring shaft surface
• 0.3125-inch (5/16-inch) bore diameter for standard fractional shaft sizes
• Steel construction provides strength and durability in mechanical drive applications
• Pack of 5 collars supports multi-point installations and service inventory
• Compact form factor suitable for space-constrained shaft assemblies

Compatibility

Designed as an OEM-style replacement or maintenance component for mechanical assemblies using 0.3125-inch diameter shafts. No specific model compatibility data was provided by the manufacturer for this part number.

Installation Notes

Installation of shaft clamp collars is typically performed by millwrights, mechanical technicians, or maintenance trades. Always de-energize and lock out the drive system before installing or adjusting collars on any rotating shaft. Position the collar at the desired shaft location, then tighten the clamping fastener evenly to secure it in place. Do not over-tighten, as this can distort the collar bore or damage the shaft surface.
