32307 / 7607E Tapered Roller Bearing | 35×80×32.75mm | Single Row Metric | Cr=116 kN | Combined Radial + Axial Load | ISO Standard | GOST 7607E Equivalent | NEXANS Bearing

The 32307 is the entry-point model of the NEXANS 32300 series — the smallest bore (35mm) in this heavy-duty metric tapered roller bearing family. Its notably wide cross-section (T=32.75mm) relative to bore size (d=35mm) is characteristic of the 32300 heavy series, delivering high load capacity in a compact envelope. NEXANS Bearing supplies the complete 32300 series from 32307 (35mm bore) through 32252 (260mm bore), all manufactured to ISO standards with GOST certification available.

Series Note: The 32307 is the smallest bore entry point of the NEXANS 32300 series at 35mm bore — one step smaller than the 32308 (40mm). The series scales up to 260mm bore (32252), covering the full range of heavy industrial shaft sizes. All models carry GOST equivalents for Russian/CIS market compliance.

32307 vs Adjacent 32300 Series Models

Model	d (mm)	D (mm)	T (mm)	Weight (kg)	Cr (kN)	Source
32307	35	80	32.75	~0.78	116
32308	40	90	35.25	~1.03	133
32309	45	100	38.25	1.42	~153
32310	50	110	42.25	1.88	~176
32311	55	120	45.5	2.39	~200

Key Insight: The 32307 at 35mm bore / 116 kN is the lightest and most compact entry in the 32300 series — ~0.78 kg vs 32308's ~1.03 kg. As bore increases, both weight and load capacity increase progressively. Choose 32307 for medium-duty gearbox and axle applications where the smallest 32300-series footprint is needed.

FAQ

Q1: What is the difference between 32307 and 7607E?

32307 is the ISO/DIN international designation. 7607E is the Russian GOST standard equivalent — identical dimensions (35×80×32.75mm) and specifications. NEXANS holds GOST certification, making the 32307/7607E directly usable in Russian and CIS market machinery.

Q2: What is the dynamic load rating of 32307?

The dynamic load rating (Cr) is 116 kN, independently confirmed by Timken-brand equivalent data from Quality Bearings Online. Significantly higher than a same-bore deep groove ball bearing (e.g., 6307: Cr≈35.1 kN), reflecting the superior load capacity of tapered roller geometry.

Q3: How does 32307 compare to 32308?

The 32307 (35mm bore) is the smaller, lighter entry model vs 32308 (40mm bore): T=32.75mm vs 35.25mm, weight ~0.78 kg vs ~1.03 kg, Cr=116 kN vs 133 kN. Both share the same 32300 heavy series design philosophy. Choose 32307 for 35mm shafts; 32308 for 40mm shafts.

Q4: How does 32307 compare to 32207 (same bore, different series)?

Both have 35mm bore, but the 32307 (heavy 32300 series) has T=32.75mm vs 32207 (light 32200 series) T≈24.25mm. The wider 32307 delivers significantly higher load capacity at the cost of greater axial space. Choose 32307 for heavy-duty applications; 32207 for space-constrained light-duty use.

Q5: What is the weight of 32307?

The 32307 weighs approximately 0.76–0.8 kg, confirmed by two independent sources: Quality Bearings Online (0.76 kg, Timken brand) and Bearing King UK (0.8 kg). It is the lightest bearing in the entire 32300 series.

Q6: Is the 32307 separable?

✅ Yes. Like all tapered roller bearings, the 32307 is separable — the cone (inner ring + rollers + cage) and cup (outer ring) can be separated, greatly simplifying installation in blind housings and facilitating maintenance.

Q7: Does NEXANS supply the complete 32300 series?

✅ Yes. NEXANS Bearing supplies the complete 32300 series from 32307 (35mm bore) through 32252 (260mm bore) — all models in stock from 3,000m² warehouse with GOST certification available.

Q8: Is OEM/private label available?

✅ Yes. NEXANS Bearing provides full OEM and private label services — custom branding, packaging, and documentation. Agents established in 30+ countries.
