When your RV slide-out starts binding, grinding, or refusing to travel smoothly, a worn roller bearing is a common culprit. The Lippert 118353 is the correct OEM-spec replacement bearing for LCI above-floor slide-out mechanisms -- restoring smooth, reliable operation without the guesswork of sourcing an off-spec substitute.
The Lippert 118353 roller bearing is a direct replacement part designed specifically for LCI (Lippert Components Inc.) above-floor slide-out systems found on a wide range of travel trailers, fifth wheels, and motorhomes. The thread spec and overall length are machined to OEM tolerances, so you are not adapting a generic bearing into a precision system.
This is also cross-referenced as Keystone RV Part Number 338675, making it a straightforward warranty or service replacement for Keystone-branded coaches equipped with LCI above-floor slide-out assemblies. The part arrives ready to install -- no pressing, staking, or sub-assembly required.
3/8 in., 24 thread pitch -- matches LCI above-floor slide-out hardware exactly. No re-tapping or adapters needed.
1-3/8 in. overall length keeps bearing engagement and slide travel within factory-spec tolerances.
No assembly required. Remove the worn bearing, thread in the replacement, and get your slide-out moving again.
Manufactured domestically to Lippert quality standards and backed by a limited 1-year manufacturer warranty.
LCI above-floor slide-out systems use a rack-and-pinion or schwintek-adjacent roller mechanism to guide the slide room along its travel path. The roller bearings carry lateral and vertical load as the room extends and retracts, keeping it level and preventing the slide box from dragging against the floor or sidewall. A failed bearing causes uneven travel, noise, and -- if ignored -- accelerated wear on the rack, the room seal, and the slide motor itself.
Replacing a worn bearing early is the lowest-cost intervention in slide-out maintenance. This part is light enough (0.5 lbs.) to keep as a spare in your service kit for roadside or campsite repairs.
LCI above-floor slide-out systems differ from Schwintek in-wall systems and from under-floor hydraulic systems. Confirm your slide type before ordering:
