0The drawn cup needle roller bearings from Suma Bearing Supplierare needle roller bearings with the deep drawn, thin-walled outer ring with either an open end or closed end.
Our NUTR series are yoke-type track roller bearings (also known as cam followers or needle roller track rollers). Designed with a thick-walled outer ring and full complement needle rollers, they provide high radial load capacity and shock resistance.
Yoke type design: Mounts directly on a shaft or pin (no stud).
Full complement needle rollers: Maximum load capacity for cam drives and track systems.
Grease-lubricated and sealed: Ready to install, maintenance-free under normal conditions.
Interchangeable: Dimensions match major brands (INA, SKF, FAG, NSK).
Wide size range: From NUTR 15 (15mm bore) to NUTR 50110 (50mm bore).

Common Applications for NUTR Yoke Track Roller Bearings
Due to their high load capacity and compact design, NUTR series bearings are widely used in:
Cam drives & indexing tables: Precise motion control in packaging and assembly machines.
Conveyor systems: Track rollers for curved or linear guides.
Material handling equipment: Lift tables, palletizers, and AGVs.
Machine tool automation: Tool changers and linear motion systems.
Printing and converting machinery: Web guiding and tension control.
A: NUTR bearings have a full complement of needle rollers for maximum load capacity. NATR bearings have a cage-guided needle roller set, allowing higher speeds but lower load capacity. Choose NUTR for heavy-load, low-to-medium speed applications.
A: Yes. Our NUTR series dimensions, tolerances, and load ratings are designed to meet international standards. NUTR 15, NUTR 30, NUTR 50110 directly replace INA, SKF, and FAG equivalents. Contact us for cross-reference verification.
A: Yes. The thick-walled outer ring and full complement needles make NUTR ideal for cam followers with impact loads. The dynamic load rating (Cw) for NUTR 30 72 is 46,000 N, and static (Cow) is 62,800 N. Ensure the mounting shaft meets tolerance recommendations.
A: They are delivered pre-greased and sealed. For normal operating conditions (≤ 80°C, no water ingress), they are maintenance-free. For high-speed or wet environments, periodic relubrication through the provided lubrication hole (if equipped) is recommended.
A: Yes. We can produce NUTR series with inch bore sizes, special seals (e.g., Viton for high temperature), or anti-corrosion coatings (Zn-phosphating, black oxide). Minimum order quantity may apply. Please contact us with your requirements.
