Drawn cup needle roller bearings<\/h1><\/div>\n\n\n\n

Drawn cup needle roller bearing is a type of bearing that uses long, thin cylindrical rollers (needles) to support radial loads. The “drawn cup” refers to the method of manufacturing the outer race, which is made from a thin-walled steel cup that is drawn into shape. This design allows for a compact bearing with a high load-carrying capacity.<\/p><\/div>\n\n\n\n

The absence of a cage allows for more needle rollers, which significantly increases the radial load-carrying capacity compared to caged types of the same size.
Because the rollers are in direct contact with each other (no cage to separate them), these bearings are not suitable for high-speed applications. Friction and heat generation are higher at elevated speeds.
Available in both open-end (both sides open) and closed-end (one side closed) versions, depending on application needs.<\/p><\/div><\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n

These bearings have seals (usually rubber or synthetic material) on one or both sides. The seals help prevent the ingress of dust, dirt, and other contaminants. They also help retain lubricant inside the bearing, improving reliability and reducing maintenance.<\/p><\/div><\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n

Open End Drawn Cup Needle Roller Bearings<\/strong>

<\/strong>Features: Open at both ends, allows shaft to pass through. Applications:
Automotive transmissions and gearboxes
Two-stroke engines (connecting rods)
Agricultural machinery
Textile machinery
Power tools

Closed End Drawn Cup Needle Roller Bearings<\/strong>

<\/strong>Features: One end is closed, suitable for shaft end mounting. Applications:
Electric motors (supporting shaft ends)
Automotive starters
Small gearboxes
Pumps

Sealed Drawn Cup Needle Roller Bearings<\/strong>

<\/strong>Features: Equipped with seals to retain grease and exclude contaminants. Applications:
Automotive components (e.g., steering columns, transmissions)
Home appliances (washing machines, vacuum cleaners)
Office equipment (printers, copiers)
Power tools (drills, grinders)<\/p><\/div><\/div><\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n

Maximum Radial Load in Minimum Space<\/strong><\/h2>\n\n\n\n

When radial space is at an absolute premium, standard machined-ring bearings are simply too bulky. ZMS Drawn Cup Needle Roller Bearings<\/strong> are the ultimate low-profile solution. They feature a unique, thin-walled outer ring precisely deep-drawn from high-quality sheet steel. This incredibly thin cross-section allows engineers to maintain a large shaft diameter for maximum rigidity, while still providing an exceptionally high radial load-carrying capacity.<\/p>\n\n\n\n

HK (Open End) vs. BK (Closed End) Designs<\/strong><\/h2>\n\n\n\n

HK Series (Open Ends):<\/strong> The standard design, open on both sides, allowing the shaft to pass completely through. Ideal for general gearboxes and power tools.<\/p>\n\n\n\n

BK Series (Closed End):<\/strong> One end of the drawn cup is completely sealed. This closed design is perfect for shaft ends, acting as a highly effective, space-saving seal to prevent grease leakage and block contaminants from entering the bearing arrangement.<\/p>\n\n\n\n

Direct Housing Installation (No Axial Location Required)<\/strong><\/h2>\n\n\n\n

One of the greatest engineering advantages of drawn cup needle roller bearings is their installation simplicity. Because the thin-walled outer ring is designed to be press-fitted tightly into the housing bore, it creates a rigid interference fit. This means no additional axial locating methods<\/strong> (like snap rings or shoulders) are required, drastically simplifying housing design and reducing assembly time for high-volume OEM production.<\/p>\n\n\n\n

Caged vs. Full Complement Options<\/strong><\/h2>\n\n\n\n

Cage-Guided:<\/strong> Utilizing a steel or polyamide cage to guide the needle rollers, this is the standard choice for high-speed applications (e.g., automotive alternators), ensuring excellent grease retention and low friction.<\/p>\n\n\n\n

Full Complement:<\/strong> For extremely heavy-duty, slow-oscillating applications (e.g., agricultural machinery joints), we offer full complement designs packed with the maximum number of rollers to deliver the highest possible load rating.<\/p>\n\n\n\n
