30205 Tapered Roller Bearing

The 30205 is a single-row metric tapered roller bearing for combined radial and one-direction axial loading. It uses a separable cup and cone, so paired arrangement, mounting setting, lubricant and external sealing must be reviewed as part of the assembly.

Product Overview

The 30205 is a single-row metric tapered roller bearing for combined radial and one-direction axial loading. It uses a separable cup and cone, so paired arrangement, mounting setting, lubricant and external sealing must be reviewed as part of the assembly.

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.

30205 engineering context

30205 Tapered Roller Bearing Overview

The 30205 is a single-row metric tapered roller bearing. Its cup-and-cone geometry can support combined radial and one-direction axial load when the complete bearing arrangement, setting and mating parts are correctly specified.

The dimensions and technical values on this page are engineering reference data. The exact offered configuration, internal design, tolerances, lubricant and performance data remain subject to quotation and drawing review.

Selection review

30205 Selection Considerations

  • Confirm the 25 mm shaft size and the required shaft fit.
  • Record radial load, axial load direction and duty cycle.
  • Review mounting conditions, available adjustment and the paired-bearing arrangement.
  • Confirm lubrication, external sealing, operating temperature and alignment before approval.

Applications

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

Replacement / Interchange

Possible search and drawing-reference candidates:

  • 30205 basic designation
  • 30205 J2/Q dimensional candidate
  • 30204 / 30206 adjacent sizes—not direct replacements
Not an automatic replacement. Match bore diameter (d), outside diameter (D), total width (T), and where applicable inner-ring width (B) and outer-ring width (C), together with internal design, preload or clearance, lubrication and load requirements before any substitution is approved.
