The Bomag 05741128 O-Ring is a genuine OEM sealing component designed for Bomag tandem rollers across the BW 100, BW 120, BW 125, BW 115, BW 131, BW 135, and BW 138 series. Sourced directly from Bomag, this O-Ring matches the original equipment specification for material grade and dimensional tolerancing. This O-Ring covers an extensive range of tandem roller variants including the BW 100 AD-4, BW 120 AD-5, BW 125 AC-4, BW 138 AD-5, BW 131 AD-5, BW 120 SL-5, BW 120 SLC-5, BW 120 AD-5 CC, and more. Ordering by part number 05741128 ensures you receive the correct seal the first time.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's exact material compound and dimensional specifications, delivering the same fluid and pressure containment as the original seal
- Drop-In Replacement — engineered to the original groove dimensions and cross-section so this O-Ring seats correctly without modification
- Broad Tandem Roller Coverage — fits BW 100, BW 115, BW 120, BW 125, BW 131, BW 135, and BW 138 series tandem rollers across multiple generation variants including -3, -4, and -5 models
- Leak Prevention — a compromised O-Ring allows hydraulic fluid or lubricant to escape, leading to pressure loss and accelerated wear on surrounding components; replacing it promptly keeps sealing surfaces protected
- Positive Part Number Verification — ordering by Bomag part number 05741128 confirms an exact match to the original component, eliminating guesswork when sourcing a seal for your tandem roller
An O-Ring is a loop-shaped elastomeric seal that sits in a machined groove between two mating surfaces or around a moving shaft to prevent the passage of fluid or air. In tandem rollers like the BW 100 and BW 120 series, O-Rings are used throughout hydraulic circuits, drum drive assemblies, and fluid reservoirs to maintain system pressure and keep contaminants out. When an O-Ring degrades, flattens, or develops a nick, it loses its sealing ability — resulting in fluid leaks, pressure drop, and potential damage to the components it was protecting.
