NSK 3308 B ZZ TNG C3 - Double Row Angular Contact Ball Bearing 40x90x36.5 mm

The NSK 3308 B ZZ TNG C3 is a double row angular contact ball bearing with dimensions 40x90x36.5 mm, engineered for demanding applications requiring maximum stability, precision, and long service life. Its “B” contact angle design (25°) allows it to handle both radial and axial loads in both directions, while the ZZ shields provide reliable protection against contaminants. The TNG cage (PA66 glass-fiber reinforced) and C3 clearance ensure durability, resistance to heat, and smooth performance at higher speeds.

FAQ

Q1: What is a double row angular contact ball bearing?
It is a bearing with two rows of balls in an angular arrangement, allowing it to support high axial and radial loads simultaneously.

Q2: What does TNG C3 mean?
TNG refers to a glass-fiber reinforced polyamide cage for improved strength and heat resistance, while C3 indicates greater internal clearance, ideal for high-speed or high-temperature use.

Q3: Are ZZ shields maintenance-free?
Yes, the shields provide long-term protection against dust and debris while maintaining lubrication.

Q4: What are the exact dimensions of NSK 3308 B ZZ TNG C3?
Inner diameter: 40 mm, outer diameter: 90 mm, width: 36.5 mm.
