PRODUCT INTRODUCTION     

                                                                                                                                                              

Benefits of a Grease Bath Trailer Axle

1. Superior Lubrication & Reduced Friction
The axle is submerged in grease, ensuring constant lubrication of bearings and races.
Reduces wear and heat buildup, extending component life.
Better performance under heavy loads and high-speed towing.

2. Lower Maintenance Requirements
Unlike traditional axles that need frequent greasing, a grease bath system is sealed, reducing maintenance intervals.
No need for bearing buddies or manual repacking-just periodic grease level checks.

3. Enhanced Durability & Longevity
The sealed design keeps out dirt, water, and debris, preventing corrosion and bearing failure.
Ideal for harsh environments (mud, water, dust) where standard bearings might fail.

4. Improved Heat Dissipation
Grease absorbs and distributes heat better than dry-packed bearings, reducing the risk of overheating during long hauls.

5. Better for High-Capacity Trailers
Commonly used in heavy-duty applications like boat trailers, utility trailers, and agricultural equipment.
Handles continuous submersion (e.g., boat launches) better than standard bearings.

6. Cost-Effective Over Time
Fewer bearing replacements and less downtime mean long-term savings.

ACCURATELY MEASURE YOUR TRAILER AXLE

                                                                                                                                                              

1. HUB FACE
(1)--Prepare the axle: Remove the wheels and tires from the axle to expose the hub faces. 
(2)--Locate the hub face: The hub face is the flat surface on the hub where the wheel sits flush against it. 
(3)--Use a straight edge: Place a straight edge against the hub face on one side of the axle. 
(4)--Measure across the axle: Place the end of your tape measure against the straight edge and extend it across the axle to the corresponding hub face on the other side. 
(5)--Read the measurement: The measurement on your tape measure is the hub face measurement. 


2.SPRING CENTER
(1)--Locate the spring pads: Identify the pads on the axle where the leaf springs are mounted.
(2)--Find the center: For each spring pad, find the center point of the bolt hole.
(3)--Measure: Use a tape measure to measure from the center of the bolt hole on one spring pad to the center of the bolt hole on the opposite spring pad.
(4)--Record the measurement: This measurement is the spring center of your trailer axle.
