Top Roller LP-1015-0025-228
Worsted / Cotton Ring Spinning Top Roller
Short Staple Roving Frame Top Roller
Textile top rollers are critical components in spinning machinery, primarily found in drafting systems of machines like ring frames, speed frames (roving frames), draw frames, and combers. Their main purpose of top roller to precisely control the fibers during the drafting process to ensure high-quality and even yarn.
- A typical anti-friction spinning top roller is a precision-engineered component with several parts:
- Shell/Arbour Top roller: The core component, often made of hardened alloy steel, ground to high precision
- Anti-Friction Top Roller Bearings: They are typically fitted with double-row ball bearings to ensure smooth and silent running with minimal friction, even at high speeds and under high load capacity.
- Lubrication and Sealing in Textile Top Roller: They are usually injected with a special long-life grease and fitted with seals to prevent lubricant leakage and contamination ingress.
- Cot (Covering) Top Roller: The surface that comes into contact with the fibers is covered with a rubber cot (or sometimes synthetic materials).
- Cot Material Top Roller : Various rubber or synthetic compounds (like NBRs, CSMs, or specialized blends) are used, with properties like specific hardness (Shore A), chemical resistance, and anti-static properties tailored for different fiber types (cotton, synthetic, wool) and processes.
- Cot Hardness: Hardness ranges are common, such as 60 Shore A to 85 Shore A, depending on the machine and material being processed.
- Cot Features: Some cots can feature special surface designs, like spiral grooves, to help remove trash particles
