RHP Roller Bearings, part of the NSK Group, are designed for applications requiring robust load-carrying capacity and durability. With a range that includes cylindrical, spherical, and tapered roller bearings, RHP roller bearings are suitable for heavy-duty and high-speed operations across various industries, including automotive, mining, industrial machinery, and power generation.
The main difference between a roller bearings and a ball bearing is in the contact areas of the rolling elements. Rollers have linear contact while balls have point contact.
Roller bearings therefore have higher radial load carrying capacities, but usually operate at lower speeds due to greater friction caused by a larger contact area. This makes roller bearings more suitable for use in heavy assemblies.
Roller bearings can have either cylindrical or tapered rollers – each having unique benefits over the other and are chosen depending upon application requirements.
RHP offers three main types of roller bearings:
Selecting the right roller bearing involves considering factors such as load type (radial or axial), speed requirements, environmental conditions (temperature, dust, moisture), and alignment needs. Consulting with a technical specialist or using RHP's selection guides can help ensure you choose the most suitable bearing.
Regular maintenance includes proper lubrication, alignment checks, and inspections for wear or damage. Following manufacturer guidelines for lubrication intervals and cleaning around the bearing can help extend its service life and maintain optimal performance.
