- Continuous bearing lubrication: Keeps bearings lubricated at all times during long term operation with this wheel bearing grease, helping them run smoothly and efficiently. - Improved bearing performance: The inner bearing raceways are separated by seals, creating an empty space through which the grease can flow inward, resulting in better storage performance. Experience higher efficiency and longevity with optimized fat distribution. - Easy to use: Insert into the bearing and pump grease through the Zerk connector with your grease gun (not included). Simple, comfortable maintenance of your wheel bearings. - Compatibility and fit: Specially designed for Polaris UTV and ATV wheel bearings with an inner dimension of 44 mm (1.7 inches). Ensures a perfect fit and effective lubrication of your Polaris vehicle. - Use scenarios: - Routine maintenance on Polaris UTV or ATV to prevent dry running and extend bearing life. - After bearing service to re-lubricate 44 mm bore bearings and restore optimal performance. - On-trail or in-shop maintenance where quick greasing via the Zerk connector reduces downtime.
