629-2Z/C3LT Bearing Product Overview & Core Advantages
The 629-2Z/C3 is a metric single row deep groove ball bearing designed for reliable performance in general industrial applications. This shielded bearing offers robust radial load capacity and is characterized by its high-quality chrome steel construction. Its key advantages include effective contamination protection from the integral shields and an optimized C3 radial internal clearance, making it suitable for applications with potential thermal expansion or where fits result in a reduction of internal clearance. The design ensures stable operation and long service life.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 629 | Basic Bearing Series | Denotes a standard metric, single row deep groove ball bearing with a 9 mm bore. |
| -2Z | Shielded on Both Sides | Features non-contact steel shields that protect against contamination while allowing for high-speed operation. |
| /C3 | Radial Internal Clearance Group | Specifies a C3 clearance, which is greater than normal. This is advantageous in applications where thermal expansion is a factor or where interference fits are used. |
629-2Z/C3LT Bearing Structural Features & Performance Benefits
Optimized for Radial Loads: The single row deep groove raceway geometry is precision-engineered to carry significant radial dynamic and static loads (873 lbf and 357 lbf respectively), providing reliable support for rotating shafts.
Contamination Resistance: The 2Z shields on both sides effectively prevent the ingress of solid contaminants, enhancing bearing life and reliability in less-than-ideal environments without significantly increasing friction.
Operational Flexibility: The C3 radial internal clearance accommodates dimensional changes from thermal expansion or press-fits, preventing premature failure due to excessive preload and ensuring smooth operation.
High-Speed Capability: Manufactured to ABEC 1 | ISO P0 tolerance class and featuring a low-friction design, this bearing supports a limiting speed of 28,000 rpm, making it suitable for a wide range of high-velocity applications.
629-2Z/C3LT Bearing Typical Application Areas
