Shaoxing Shangyu Flight Seiko Machinery Co., Ltd. (FTM) is proud to present our specialized Type Track Rollers Bearing Without Inner Ring. Leveraging over 30 years of technical design expertise, we deliver high-quality, non-standard bearing solutions that meet the rigorous demands of modern industrial applications, including engineering machinery and textile machinery.
Key Product Features and Advantages
Track rollers without an inner ring are a distinct and highly advantageous type of rolling element bearing, typically utilizing a set of rollers or needles (often featuring a cage for guidance) and an outer ring.
- Exceptional Space Efficiency: The fundamental feature of this design is the absence of a dedicated inner ring, resulting in a remarkably low radial cross-section height. This is ideal for support structures with stringent radial installation space limitations, allowing for compact and weight-saving machine designs.
- High Load Capacity: Utilizing a full complement of rollers or a caged roller/needle assembly, these bearings are engineered to handle substantial static and dynamic loads. The extended contact length between the rolling elements and the raceway ensures superior bearing capacity, often making them comparable to deep groove ball bearings of similar size.
- Superior High-Speed Performance: By running directly on a hardened and ground shaft (which acts as the inner raceway), these bearings exhibit a lower coefficient of friction. This allows them to achieve limit speeds close to those of deep groove ball bearings, making them well-suited for high-speed rotation applications.
- Installation Flexibility & Simplified Maintenance: The separable design, where the outer ring assembly can be separated from the rollers/needles, offers significant installation and disassembly convenience. Maintenance and replacement become more straightforward, allowing customers the flexibility to use the hardened and polished equipment shaft as the inner raceway, or to optionally integrate an appropriate inner ring based on application requirements.

Frequently Asked Questions (FAQ)
Q: What is the main advantage of this bearing type?
A: Extremely compact radial design (low cross-section) and high load capacity for space-restricted support structures.
Q: What shaft preparation is required?
A: The shaft must be hardened, precisely ground, and polished to serve effectively as the inner raceway.
Q: How does its load capacity compare?
A: It handles heavy radial loads with superior capacity relative to its cross-section, often comparable to deep groove ball bearings.
Q: Are these bearings suitable for high speeds?
A: Yes, the low friction allows for high-speed rotation, with limit speeds approaching deep groove ball bearings.
Q: Can FTM customize the design or materials?
A: Yes, absolutely. As a non-standard bearing specialist, FTM customizes dimensions, materials, tolerances, and sealing to meet specific application requirements.
