Multiquip RB252828 Ball Plunger (3/8-16)

The Multiquip RB252828 is a genuine OEM Ball Plunger (3/8-16) designed for the JB series rebar benders, including the JB5135, JB5090, JB8090, JB11090, JB7135, JB7090, JB9180, and JPU1. As a direct factory replacement, this part carries the same specifications as the original component installed at the time of manufacture. Sourcing the RB252828 from an authorized Multiquip parts distributor ensures you are receiving a component that meets the exact design criteria for your machine. DHS Equipment stocks this part to keep your rebar bending operations on schedule.

Key Features

• Genuine OEM Construction: — Machined to the original thread specification (3/8-16), ensuring consistent spring tension and ball engagement that a worn or undersized plunger cannot deliver.
• Direct-Thread Installation: — The 3/8-16 thread profile installs directly into the existing tapped bore on supported JB series benders without any reworking of the housing.
• Broad JB Series Compatibility: — Confirmed fitment across JB5090, JB5135, JB7090, JB7135, JB8090, JB9180, JB11090, and JPU1 rebar benders.
• Precise Detent Control: — A correctly functioning ball plunger maintains positive indexing and detent positioning during the bend cycle; a worn unit causes inconsistent stops and inaccurate bend angles.
• Operational Safety: — Reliable detent engagement is essential in rebar bending equipment where unintended movement during a bend can create a hazard for the operator.

A ball plunger is a spring-loaded fastener component that uses a small hardened ball and an internal spring to create a positive detent or indexing point in mechanical assemblies. In rebar bending equipment, it holds moving components in a defined position during the setup or bend cycle, giving the operator a tactile confirmation that the mechanism is correctly seated before the bend is initiated. When the ball plunger wears or loses spring tension, indexing becomes imprecise, leading to inconsistent bend angles and potential slippage during operation.
