W 6004-2RS1/VP311 Bearing Product Overview & Core Advantages
The W 6004-2RS1/VP311 is a single row deep groove ball bearing designed for high reliability and long service life in demanding applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantages include the ability to handle significant radial loads, consistent performance across a wide temperature range from -30°C to 120°C, and a sealed design that retains lubrication and excludes contaminants, ensuring maintenance-free operation.
Model Code Breakdown
- W: Indicates a bearing with a stainless steel construction.
- 6004: The basic bearing series, defining the standard dimensions: 20mm bore, 42mm outside diameter, 12mm width.
- 2RS1: Signifies that the bearing is fitted with two contact seals (one on each side), providing effective protection against contamination and grease loss.
- VP311: Denotes the specific type of grease lubricant pre-packed into the bearing, optimized for its performance characteristics.
W 6004-2RS1/VP311 Bearing Structural Features & Performance Benefits
The bearing's performance is derived from its robust construction. The single row deep groove raceway is precision-engineered to facilitate smooth operation and efficient radial load support. The stainless steel cage ensures stability at high rotational speeds, contributing to the bearing's limiting speed of 11,000 rpm. The contact seals (2RS1) are a critical feature, creating an effective barrier that retains the grease lubrication and prevents the ingress of moisture and solid particles, significantly extending service intervals. With a standard CN radial internal clearance and P0 tolerance class, it delivers reliable and consistent performance for a wide range of general industrial applications.
