Precision Industrial Bearings for Textile Machinery OEM & Custom Replacement
Textile machinery operates under high speed, continuous vibration, and constant exposure to cotton lint and dust. These industrial bearings are designed for spinning frames, weaving looms, and finishing lines. Made from high-purity alloy steel with strict clearance controls, they reduce friction and heat during multi-shift operations. Their dimensions follow international standards, allowing them to fit directly into major equipment assemblies and prevent unexpected production stoppages.

Deep Groove Ball Bearings
Used for high-speed motor drives and general transmission shafts. They feature low noise and dual-lip rubber seals to block fine cotton and synthetic dust.
Spherical Roller Bearings
Built for heavy loads and high-vibration areas on sizing and calendering rolls. They handle angular misalignment up to 2.5 degrees without placing stress on the load path.
Materials & Surface Treatments
Bearing Steel (GCr15 / AISI 52100)
Through-hardened high-carbon chromium steel. It provides a uniform internal structure, high strength, and resistance to metal fatigue from rolling contact.
Stainless Steel (AISI 440C / 304)
Corrosion-resistant steel used in wet processing, dyeing, and washing machines where water and chemicals are always present.
Black Oxide Treatment
A chemical coating applied to rings and rolling elements. It improves initial break-in performance, holds micro-lubrication better, and stops surface rust.
Polyamide (PA66) and Brass Cages
Machined brass cages for heavy shock loads, and glass fiber-reinforced plastic cages for lightweight, high-speed applications.
Applications
Air-Jet and Water-Jet Looms
Main drive shafts, shedding parts, and take-up rollers running at speeds over 1,000 RPM.
Ring Spinning Frames
Spindle inserts, cylinder shafts, and drafting roller parts that need low vibration and steady torque transmission.
Textile Dyeing and Finishing Lines
Wet-process guide rollers, squeeze rolls, and drying cylinder journals exposed to liquid chemicals and high heat.
Non-Woven Production Lines
Carding machines and needle-punching units that face constant heavy loads and fiber dust.

Custom Bearing Manufacturing
Dimensional Changes:
Non-standard inner diameters, outer diameters, and custom ring widths.
Custom Seals:
Special fluoroelastomer (Viton) seals for chemical resistance, or lab seals for heavy lint environments.
Special Shapes:
Modified internal designs, custom oil grooves, and special mounting flanges.
From Prototype to Volume Production:
Fast CNC turning, automated grinding lines, and material testing ensure a smooth shift from sample approval to full production.
Forging and Turning: CNC turning centers keep raw rings centered and leave the right amount of metal for heat treatment.
Heat Treatment: Controlled-atmosphere furnaces heat and cool the metal evenly to reach the correct core strength and surface hardness (58 to 62 HRC).
Precision Grinding and Honing: Multi-step grinding lines control roundness, surface finish (Ra <= 0.1 um), and ball roundness down to the micrometer level.
Inspection and Testing:
• 3D Coordinate Measuring Machines (CMM) to check dimensions.
• Roundness testers to check shape accuracy.
• Spectrometers to test raw metal chemical composition.
• 100 percent noise and vibration checks before packing.
How to Choose the Right Bearing
Check Load and Direction:
Decide if the position faces radial loads, axial loads, or both. Use cylindrical rollers for heavy radial loads and deep groove bearings for combined loads.
01
Review Speed Limits:
Look at operational RPM and cage limits to keep the bearing from overheating and seizing.
02
Analyze the Environment:
Choose contact rubber seals or metal shields based on how much cotton lint, chemical, or water is present.
03
Check Space Limits:
Measure shaft and housing fits carefully to stop parts from slipping or warping under tight pressure fits.
04
Confirm Lubrication:
Match the grease type and oil thickness to the working temperature and how often re-greasing is needed.
