6203-ZZ Shielded Deep Groove Ball Bearing

The generic 6203-ZZ designation describes the 6203 envelope with metal shields on both sides. Shields retain grease with less contact friction than typical 2RS seals, while protection against moisture and fine contamination depends on the exact shield gap and application.

Product Overview

The generic 6203-ZZ designation describes the 6203 envelope with metal shields on both sides. Shields retain grease with less contact friction than typical 2RS seals, while protection against moisture and fine contamination depends on the exact shield gap and application.

LTO supports OEM buyers, distributors and industrial users with suffix review, drawing-controlled requirements, private-label packaging and export documentation. Availability, minimum order quantity and production data are confirmed in the quotation.

Applications

The bearing number is only the starting point. Load, speed, temperature, contamination, alignment and service-life targets determine the final selection.

These industry links are engineering review paths, not model-specific recommendations. Final bearing selection should be confirmed against the actual load, speed, fit, clearance, lubrication, environment and application requirements.

07 · Cross-reference screening

Replacement / Interchange

Possible search and drawing-reference candidates:

  • 6203-ZZ basic dimensional designation
  • 6203-2Z engineering reference—not verified interchangeable
  • Confirm internal clearance, precision, cage, enclosure, lubricant and offered manufacturer data
Not an automatic replacement. Match bore diameter (d), outside diameter (D), width (B), internal clearance, sealing, cage, precision, lubrication and load requirements before any substitution is approved.
