32232DF Pre-Matched Face-To-Face Tapered Roller Bearing DF Arrangement 160x290x168mm Heavy Mining Reducer Equipment

The 32232DF is a factory pre-matched face-to-face (DF/X arrangement) double set of single row 32232 tapered roller bearings with standard intermediate spacer ring. DF layout can withstand heavy radial load and bidirectional axial thrust simultaneously, with strong anti-overturn rigidity. Pre-adjusted internal clearance eliminates manual pairing errors, widely applied in large mining reducers, metallurgical rolling mills, heavy construction machinery and heavy-duty vehicle transmission shafts.

• DF face-to-face layout diverges load lines toward bearing axis, excellent anti-tilting rigidity
• Factory pre-matched set with standardized spacer, fixed clearance, no on-site pairing adjustment
• Two groups of crowned tapered rollers share heavy radial load, support two-way axial force
• Separable cone & cup structure for convenient disassembly, maintenance and component replacement
• Optimized roller crowning reduces edge stress, lowers heat generation under continuous heavy impact
• DB back-to-back matched set and J2 reinforced cage versions can be customized

This DF pre-matched tapered roller bearing set is widely used in:

• Mining ball mill reducers, ore crusher heavy drive assemblies
• Metallurgical rolling mill transmission shafts and large industrial speed reducers
• Heavy-duty lifting equipment, port hoisting rotary supporting parts
• Large construction machinery, heavy truck main transmission and differential components
