⚙️Product Description:
The 310-7223A (16.2x33x8.25mm) is a specialized high-capacity drawn cup / machined needle roller bearing specifically engineered for textile machinery and high-speed spinning equipment. Built with a thick-walled precision steel outer ring, high-precision GCr15 needle rollers, and a reinforced steel cage, this non-standard metric bearing offers an extremely low cross-section profile combined with exceptional radial load carrying capabilities under continuous, high-frequency oscillatory motion. We supply our cost-effective proprietary RMO brand 310-7223A textile bearings alongside flexible global brand sourcing solutions to keep your mill production running smoothly with minimum downtime.

⚙️Product Features:
- Optimized Textile Grade Design: Special 16.2mm bore and 8.25mm width dimensions tailored for seamless fitment into proprietary textile equipment drive shafts.
- High Radial Load Density: Full-complement or rigid guided needle roller assembly maximizes contact area, handling high radial impacts in compact mounting envelopes.
- Case-Hardened GCr15 Steel: Precision-ground outer raceways and hardened needle rollers provide high fatigue strength and resistance against yarn lint contamination wear.
- Reinforced Rigid Cage: Steel cage structure ensures stable needle spacing and prevents tilting during rapid start-stop cycles and high RPM shaft rotation.
- Dual Brand Sourcing Options: Available in our factory-direct RMO brand for maintenance cost optimization, as well as original sourcing from major global bearing manufacturers.
⚙️Product Application:
- Ring Spinning and Twisting Frames: Draft roller drives, spindle wharves, and tension pulley shafts in textile yarn spinning machinery.
- Rotor Spinning and Weaving Looms: High-speed rotor box guide units, rapier loom drive mechanisms, and warp let-off assemblies.
- Knitting and Printing Machinery: Circular knitting machine cam boxes, fabric take-up rollers, and textile dyeing machine drive shafts.
- Precision Industrial Gearboxes: Compact high-torque reduction gears and textile machine bobbin winding mechanisms.
⚙️Precautions:
| 1. Keep clean | 2. Use with caution | 3. appropriate tool | 4. Hot-loading | 5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
