Description
Overview
The Bearing Protect & Covers RWB1190, also known as Hub Mates, are designed to fit standard 1 3/4″ (45 mm) trailer hubs. Each unit has a spring-loaded mechanism and a grease nipple so you can easily apply grease to the bearing and inner hub. This design keeps water and grit out of the wheel hub, which improves bearing life and reduces maintenance downtime.
Features
• Chrome-plated steel construction for corrosion resistance.
• Spring-loaded action that maintains internal hub pressure.
• Grease nipple for fast bearing lubrication without removal.
• Supplied as one pair (two Hub Mates) with soft plastic protective covers.

Compatibility and Fitment
These bearing protectors fit most trailer hubs with a 45 mm (1 3/4″) bore. The spring mechanism keeps grease under pressure, while the supplied plastic caps give an additional barrier against spray and debris. Fitment is straightforward: press the protector into the hub and ensure the nipple is accessible for future servicing.
Compliance and Safety
When towing on public roads, hub integrity is critical. Always maintain lubrication and check seals before long trips. For further information on stainless and chrome materials used in marine conditions, see the ASSDA technical library.
