Item name: Compression Bearing Conveyor Ball Type: Window Rollers Model number: CKCYTB Size: CY19b(Nylon ball) Quantity: 4pcs per lot Material options: 304 stainless steel, carbon steel, nylon. Three material choices available for base and ball What this part does The CKCYTB compression bearing conveyor ball is a compact rolling element designed to restore or improve smooth linear movement in window rollers and small conveyor systems. The compression bearing design centers the ball under load for stable rotation and reduced friction, making it suitable for applications that require low noise and consistent rolling performance. Key benefits Smooth operation and low friction that reduce sticking and binding during sliding motion Durable material choices to match application needs: corrosion resistant 304 stainless steel, strength carbon steel, or low noise nylon Interchangeable combinations for base and ball allow tailoring of wear, load response, and noise level Compact CY19b size fits standard installations that accept this dimension, enabling straightforward replacement Supplied as 4 pieces per lot to cover common and maintenance needs Compatibility and performance Model CKCYTB fits installations designed for CY19b size rolling elements Material option selection lets you optimize for wear resistance, load capacity, or quiet operation depending on the environment Compression bearing geometry provides centered load support and predictable rolling behavior under typical window roller and light conveyor loads Typical use scenarios 1) Window roller replacement: Swap worn rollers in residential or commercial sliding windows to restore smooth opening and closing and to reduce rattling. 2) Light conveyor guide wheels: Use in small conveyor sections or transfer guides to maintain steady item movement and reduce friction at contact points. 3) Furniture and partition slides: Install in drawer slides or sliding partitions where low noise and reliable rolling are required. Installation and maintenance Designed for simple replacement in existing mounts that accept CY19b size components Minimal maintenance required; material choice affects inspection intervals based on load and environment Ordering details CKCYTB compression bearing conveyor ball Size CY19b(Nylon ball) 4pcs per lot Material options: 304 stainless steel, carbon steel, nylon Select the material combination that matches load, wear, and noise requirements for your application.
