Technical Deep Dive

Load Calculation

Our in-house engineers apply ISO 281 / ABMA standards for equivalent dynamic load (P), adjusted life calculation (Lnm) and contamination factor (eC) -- optimized for your specific working conditions.

Formulas Applied

L₁₀ = (C/P)ᵖ × 10⁶ rev

Lnm = a₁ × aISO × L₁₀

P = X·Fr + Y·Fa

Failure Analysis

We diagnose premature failure root causes -- fatigue spalling, false brinelling, fretting corrosion, misalignment wear and seal failure -- and provide written technical reports with corrective action plans.

Fatigue Spalling
False Brinelling
Fretting Corrosion
Misalignment Wear
Seal Failure

Material & Heat Treatment

Timken proprietary steel alloys with controlled through-hardening and case carburizing. Surface hardness HRC 58-65, core toughness optimized for shock absorption in heavy-load cycles.

Raceway

HRC 60-64

Core

HRC 30-45

Steel Grade

52100 / M50

Cleanliness

EP / XL Grade

Lubrication Guidance

Recommended grease: NLGI Grade 2-3 lithium complex or polyurea for high-temperature applications. Relubrication interval calculated per Timken lubrication guide based on speed factor (ndm) and load ratio (C/P).

Mounting & Fit

Shaft fit: k5/m5 (interference) for rotating inner ring. Housing fit: H7/JS7 for normal loads. Thermal or hydraulic mounting recommended for bore ≥ 80mm to prevent raceway damage during installation.

Service Life Targets

Designed to meet or exceed OEM service life targets under specified load and speed conditions, with proper lubrication and mounting.
