Description

1" Steel Split Lock Collar – Keyed, 2-Piece Clamp for Racing Applications


The 2518S 1-Inch Steel Split Lock Collar is a precision-machined, two-piece, two-bolt clamp collar designed for a secure, balanced hold on 1" keyed shafts. The split design allows for easy installation without the need to slide it over the end of the shaft, making it ideal for use on fully assembled go-karts, racing lawnmowers, and performance chassis setups.


This collar includes a 1/4" keyway, offering superior torque resistance and alignment on keyed axles or tubing. It's commonly used to lock down hubs, sprockets, brake systems, and steering components, helping reduce flex, misalignment, and unwanted movement during aggressive race conditions.


Common Racing Applications:

  • Secure sprocket hubs and brake hubs on live axles
  • Limit lateral movement of axle bearings
  • Lock wheel hubs in position to improve handling
  • Clamp steering and chassis components with precision


Lock Collar Specifications:

  • Inside Diameter (ID): 1.00"
  • Outside Diameter (OD): 1.760"
  • Width: ~0.500"
  • Keyway: 1/4"
  • Material: Steel
  • Design: Two-piece with dual-bolt clamp


Key Features:

  • Two-piece design applies even clamping force without shaft damage
  • Machined steel construction offers strength and durability
  • Keyed for torque stability and slip prevention
  • Versatile across multiple go-kart and mower chassis setups
  • Ideal for 1" keyed axles commonly used in racing applications

Installation Tip: Always confirm axle diameter and keyway size before ordering for best fitment and performance.

FAQ

Q1: What is the primary use of this 1" steel lock collar?

A: It's commonly used to secure sprocket hubs, brake hubs, wheel hubs, and steering components on go-karts, racing lawnmowers, and other high-performance chassis systems.


Q2: What’s the benefit of a keyed split lock collar?

A: The 1/4" keyway offers additional rotational stability and helps prevent slippage on keyed shafts during high-torque operation.


Q3: Why choose a split collar over a set-screw collar?
