INA KRV 30 PP A - Industrial Cam Follower / Track Roller

Technical Overview

The INA KRV 30 PP A is a stud-type track roller (cam follower) featuring a solid threaded stud (M12 x 1.5) and a thick-walled outer ring of Ø30 mm, width 40 mm. The full-complement needle roller design delivers a high radial basic dynamic load rating of ≈ 9 500 N and basic static load rating of ≈ 15 100 N.
Seals on both sides (PP-type) with plastic axial plain washers and NBR lip seal ensure protection in harsh environments.
Maximum grease-lubricated speed is approximately 2 100 rpm.
Engineered for longevity, the outer ring profile is optimized (INA-profile) and the full-complement needle set (no cage) increases load capacity and shock resistance.

Applications & Industrial Value

This track roller is ideally suited for industrial applications such as conveyor systems, linear guide systems, cam mechanisms and heavy-duty transport systems where a robust rolling bearing unit in a bearing housing or as part of an obudowa łożyskowa is required. Thanks to its high durability and optimized design, the KRV30-PP-A can carry high radial and axial loads resulting from misalignment or skew in the track. The inclusion of full-complement needle rollers and integrated sealing makes it particularly well-suited for environments with vibration, shock loading or contaminants. Easy installation via the threaded stud simplifies maintenance downtime.
For B2B customers seeking a reliable ball bearing equivalent or robust roller solution in demanding factory environments, this model provides effective performance and lifetime value.

Benefits for B2B Buyers

• High durability and load capacity: The absence of a cage increases the number of rolling elements, boosting load rating and extending service life.

• Reduced maintenance: The PP sealing system on both sides provides excellent protection against dust and moisture, reducing lubrication frequency and downtime.

• Simplified installation: The stud mounting (M12x1.5) enables direct fixation into mechanical assemblies saving time during integration or replacement.

• Versatility in industrial setups: Whether you need a cam follower, track roller, or bearing unit in a conveyor or linear guide, this product adapts to heavy-duty scenarios.

• Immediate availability: Stock ready for prompt dispatch from our warehouse tailored for B2B supply.

FAQ

Q: What distinguishes the INA KRV 30 PP A from standard ball bearings?
A: Unlike standard ball bearings, this unit integrates a threaded stud and a full-complement needle roller configuration (no cage), enabling significantly higher radial load capacity and improved shock resistance in cam and conveyor track applications.

Q: Can this track roller handle axial loads or misalignment?
A: Yes. The thick-walled outer ring and full-complement needle set allow the follower to absorb both radial loads and secondary axial loads resulting from track skew or misalignment, making it highly suitable for industrial linear motion systems.

Q: What maintenance is required for this bearing unit?
A: Thanks to the double-side PP sealing and integrated greasing feature (via stud or head), maintenance intervals are extended. Regular checks of lubrication and cleanliness ensure optimum performance in harsh environments.

Q: What is the operating temperature and maximum speed?
A: Typical lubrication-limited speed is approximately 2 100 rpm in grease-lubricated conditions. The sealing system supports operation in temperature ranges typically from -30°C to +100°C, depending on lubrication and ambient conditions.

Q: Is this product suitable for B2B supply and fast delivery?
A: Absolutely. The product is stocked and available for B2B orders with priority dispatch. Our warehouse is configured to support industrial clients and ensure rapid turnaround.
