6204-ZZ Shielded Deep Groove Ball Bearing

The 6204-ZZ is the double-metal-shielded version of the 6204 size. The shields help retain grease while keeping friction lower than a typical contact-sealed version, but they are not a substitute for contact seals in wet or heavily contaminated service.

Product Overview

The 6204-ZZ is the double-metal-shielded version of the 6204 size. The shields help retain grease while keeping friction lower than a typical contact-sealed version, but they are not a substitute for contact seals in wet or heavily contaminated service.

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.

06 · Application paths

Applications

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

Reference Industries for Engineering Review

Electric Motor BearingsReview operating conditions →

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:

  • 6204-ZZ
  • 6204-2Z
  • 6204-DD dimensional candidate
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.
