S636 Bearing Product Overview & Core Advantages
The S636 is a metric single row deep groove ball bearing engineered for high performance in radial load applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance and durability. This bearing is characterized by its compact design with a 6 mm bore and a high limiting speed of 27,000 rpm, making it an ideal choice for applications demanding precision, reliability, and efficient operation in challenging environments. Its ABEC1 tolerance class ensures consistent performance for a wide range of industrial uses.
S636 Bearing Model Code Explained, Specifications & Naming Convention
The S636 model code signifies a standard, open-type deep groove ball bearing. Below is a breakdown of its key implied characteristics based on its specifications:
- S6: Denotes a series of deep groove ball bearings with a specific cross-section.
- 36: Indicates a bore diameter of 6 mm (Calculation: 36 * 5 = 180, but for this specific series, it corresponds to a 6mm bore).
- Open (No Seal): The bearing is supplied without seals or shields, allowing for higher speeds and easy re-lubrication.
- Stainless Steel: All components (rings, balls, cage) are made from stainless steel, providing corrosion resistance.
- ABEC1: Specifies the precision tolerance class.
- C3 Clearance: Indicates a greater than normal radial internal clearance for applications with thermal expansion or where fits are not precise.
S636 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The use of stainless steel for the rings, balls, and stainless steel cage provides superior resistance to corrosion and contamination, extending service life in harsh conditions.
- Optimized for Radial Loads: The single row deep groove geometry is primarily designed to support significant radial dynamic load ratings (574 lbf / 2.55 kN), ensuring stable operation.
- High-Speed Capability: The open design, combined with a precision-ground raceway and a stable cage, enables a high limiting speed, suitable for demanding rotational applications.
- Standard Internal Clearance (C3): The MC3 radial internal clearance is suited for applications where operational temperatures may cause expansion, preventing pre-load and ensuring smooth running.
- Compliance & Safety: The bearing is ROHS and REACH compliant, meeting stringent environmental and safety standards for global use.
S636 Bearing Typical Application Areas
The S636 bearing is widely used in various precision instruments and machinery, including:
- Small electric motors and gearboxes
- Medical and dental equipment
- Food processing machinery
- Precision spindles and office automation equipment
- Agricultural machinery and chemical processing equipment where corrosion resistance is critical
