Timken 12 BSS - 1 Industrial Spherical Roller Bearing (SRB) | 60x110x30mm | High-Vibration Performance

The Timken 12 BSS - 1 is a premium industrial spherical roller bearing engineered for demanding heavy-load and high-vibration applications. Featuring a standard dimension configuration of 60mm bore (d), 110mm outer diameter (D), and 30mm width (B), this double-row bearing utilizes self-aligning geometry to compensate for shaft deflection and misalignment typical in harsh operational environments. Constructed with high-grade, stabilized steel and incorporating an optimized internal design (such as a brass or robust steel cage), the 12 BSS - 1 ensures superior load distribution, delivering a high basic dynamic load rating (Cr) optimized for long-term reliable service life under extreme radial and moderate axial loads. Designed specifically for critical machinery in heavy industries such as mining conveyors, pulp and paper mill rollers, gearboxes, and large pumps, the 12 BSS - 1 minimizes the risk of catastrophic failure and reduces unscheduled downtime. Its precision manufacturing, backed by Timken’s global quality assurance, ensures smooth running and high thermal stability, even at elevated operating temperatures. Choosing the 12 BSS - 1 guarantees not only performance reliability but also reduced total cost of ownership (TCO) through exceptional durability and extended lubrication intervals, making it the preferred choice for maintenance and engineering professionals prioritizing uptime.

Key Features

• Self-Aligning Capability: Accommodates severe misalignment and shaft deflection without reducing bearing life.
• Optimized Internal Geometry: Ensures high radial and axial load carrying capacity (up to 25% of radial load).
• High-Grade Material Construction: Stabilized steel heat-treated for dimensional stability and resistance to premature wear.
• Reduced Maintenance Needs: Robust sealing options (if applicable to BSS series) extend lubrication intervals in contaminated environments.
• Vibration Dampening: Designed to perform reliably in high-shock load and vibratory environments common in process industries.
