Frequently asked questions

Common questions about INA from 3G Electric.

What is the difference between INA KR and NUKR track rollers?

INA KR series track rollers use needle roller bearings, while NUKR series use cylindrical roller bearings. Needle roller designs offer a higher load capacity for a given radial space, while cylindrical roller designs can accommodate higher speeds and axial loads. Both series feature a crowned outer ring to compensate for misalignment. The choice depends on the specific load, speed, and misalignment requirements of the application. 3G Electric stocks both types in various sizes.

Are INA track rollers available with seals?

Yes, many INA track rollers are available with seals. The suffix 'PP' indicates a contact seal on both sides, which protects against dust, dirt, and moisture. For example, the KR35-PP-A has a needle roller design with a 35 mm roller diameter and M16-1.5 thread, and includes double-sided seals. Sealed versions are suitable for harsh environments. 3G Electric can supply both sealed and open designs based on your requirements.

What materials are used in INA track rollers?

INA track rollers are typically made from through-hardened bearing steel, such as 100Cr6 (SAE 52100). The outer ring, inner ring, and rolling elements are hardened to provide high wear resistance and fatigue strength. The stud is also made from hardened steel and may be phosphated for corrosion protection. Some versions may have a black oxide finish. For specific material specifications, refer to the INA catalog or contact 3G Electric for datasheets.

Can INA track rollers operate at high temperatures?

Standard INA track rollers are suitable for operating temperatures up to approximately 120°C, depending on the lubricant and seal material. For higher temperatures, special versions with heat-stabilized components or high-temperature lubricants may be available. It is important to consider the temperature limits of the seals and lubricant. 3G Electric can provide guidance on selecting the appropriate track roller for your temperature range.

How do I select the correct INA track roller for my application?

Selection depends on factors such as radial load, speed, misalignment, mounting thread size, and environmental conditions. Determine the required roller diameter and width based on the load and space constraints. Choose between needle roller (KR) and cylindrical roller (NUKR) designs based on load and speed. Consider the thread size (M12 to M24) for mounting. 3G Electric's technical team can assist with selection using INA's engineering data.

What is the lead time for INA track rollers from 3G Electric?

Lead time varies depending on the specific part number and quantity. 3G Electric maintains inventory of common INA track rollers, which can ship within 1-2 business days. For non-stock items, lead time is typically 2-4 weeks, subject to manufacturer availability. 3G Electric provides order status updates and can expedite shipments when possible.
