The Bomag 05740860 O-Ring is a genuine OEM sealing component designed for Bomag tandem rollers across multiple series, including the BW 100, BW 120, BW 125, BW 131, BW 161, BW 170, BW 174, BW 190, and BW 202 families. Sourced directly from Bomag, this O-Ring meets the exact material and dimensional tolerances specified for these machines, ensuring a proper seal in the system where it was engineered to perform. This component fits a wide range of tandem roller variants, including BW 100 AD-4, BW 100 AC-5, BW 120 AD-5, BW 161 AD-5, BW 174 AP-4i, BW 202 AD-5, and many additional configurations. Ordering by part number 05740860 confirms you are receiving the correct OEM part for your machine.
Key Features
- OEM-Grade Sealing Material — manufactured to Bomag's specified elastomer compound, delivering the correct compression set and chemical resistance for the fluid system this O-Ring seals
- Exact Dimensional Match — cross-section diameter and inner diameter conform to OEM tolerances, allowing this O-Ring to seat and compress correctly without adjustment or modification
- Broad Tandem Roller Coverage — fits a wide range of Bomag tandem rollers including BW 100, BW 120, BW 125, BW 131, BW 161, BW 174, BW 190, and BW 202 series variants across multiple generation suffixes
- Leak Prevention — a correctly installed O-Ring maintains system pressure and prevents fluid loss; a worn or damaged O-Ring leads to leaks, pressure drop, and accelerated wear on surrounding components
- Verified OEM Part — supplied as genuine Bomag with part number 05740860, eliminating guesswork and ensuring the component matches the original specification
An O-Ring is a circular elastomeric seal used to prevent fluid or gas from escaping between two mating surfaces — typically within hydraulic systems, cooling circuits, or other pressurized assemblies on a tandem roller. It works by being compressed between the joined components, creating a tight, leak-free barrier. When an O-Ring ages, hardens, or becomes physically damaged, it loses its ability to seal effectively, resulting in fluid leaks, loss of hydraulic pressure, or contamination of the system — all of which can affect the roller's steering, vibration, or drive performance.
