The bearings used in bulk material handling conveyors are expected to reliably move tons of rock, minerals or aggregate – in any weather. Considering these unique challenges, bulk conveyor operators need mounted bearings that are engineered to stand up to high loads, physical impact, and extreme contamination. Learn how premium mounted bearing solutions can help extend bearing life in the harsh outdoor conditions of mines and quarries.
Stand up to heavy loads
With the high loads and low speeds of bulk conveyor systems, you need a bearing that can perform reliably under pressure. Timken ’s broad line of mounted bearings is designed with high load ratings in mind – resulting in longer bearing life.
- Timken® mounted solid-block spherical roller bearings: Created for the harshest conditions, these units feature multiple steel-housing and locking options with complete multi-point sealing solutions (to optimize your uptime.) This drop-in solution is interchangeable with a large range of products and keeps contaminants out to optimize your efficiency.
- Timken® Type E mounted tapered roller bearings: In conveyors that experience high radial and axial loads, your plant may be vulnerable to misalignment. Available in standard solid-block and self-aligning split-block mounting styles, the Timken® Type E mounted tapered roller bearings feature engineered profiles designed to , distribute stress more evenly under high loads and/or misalignment. They also incorporate case-carburized rings and rollers, which help the bearings withstand shock loads.
- Timken® SNT mounted plummer block bearings: Keep lubrication in and contamination out. Protected by a split-design ductile iron or cast iron housing with a Timken high-performance spherical roller bearing inside, you get a versatile solution.
- Timken® SAF mounted split-block bearings: Combine fast installation with reliability in rugged environments. Available with a Timken spherical roller bearing and your choice of a cast iron, ductile iron or cast steel housing, these bearings feature split-design blocks that are easy to install – reducing servicing times.
Keep contamination out
Conveying bulk materials is a dirty job. In these harsh outdoor environments, dirt, dust, gravel, and water present a constant threat of contamination – leading to reduced bearing life. Timken mounted bearings feature an unrivaled multi-point sealing solution to help you keep the grease in and contamination out.
Using triple-lip internal and external seals, combined with a full range of bearing end covers, this high-performance sealing solution improves grease retention while reducing contamination entry. Compared to the leading competitor’s seal, Timken’s triple-barrier seals result in 7 times less water and 40% less contamination ingress – leading to a 47% longer life.
Improve impact protection with cast steel housings
When conveying rock and minerals, you need bearings that can take a hit and keep on running. TImken’s cast steel housings across its line of mounted bearings are designed to be sturdy for use in bulk conveyors.
Compared to traditional cast iron housings, cast steel can withstand significant impacts and shock loading without cracking or breaking. When combined with other enhancements like case-carburized rollers and inner rings, Timken mounted bearings can help improve your operations ‒ enabling you to avoid costly bearing damage and unexpected downtime.
From lower operating temperatures and higher load capacity to rugged sealing protection and optimized uptime, Timken bearings are engineered to give you more of what you need.
