Changzhou Hecb Bearing Co., Ltd.

Cylindrical roller bearings are a type of rolling bearing, and the NUP314 is a specific model of single row cylindrical roller bearing that features a cylindrical bore and a tapered outer ring. This design allows for easy assembly and disassembly, making it a popular choice for applications where maintenance and serviceability are critical. As a trusted single row cylindrical roller bearing supplier, we provide the NUP314 bearing 70x150x35 with strict dimensional control and full inspection to ensure it meets demanding industrial standards.

One of the key advantages of the NUP314 is its ability to handle both radial and axial loads. This makes it suitable for a wide range of applications, from heavy machinery to automotive components. Whether used in a heavy-duty machine or a precision instrument, this bearing 70x150x35 delivers consistent performance and reliability, backed by the technical support and traceability systems of an experienced single row cylindrical roller bearing supplier.

Key Features

Design: Single row, NUP type with inner ring (one rib) and a flat retaining ring for axial displacement control. This NUP314 bearing design is ideal for applications requiring high radial load capacity and moderate axial load accommodation, and it is widely recommended by any reputable single row cylindrical roller bearing supplier for heavy-duty conditions.

Dimensions: The bearing 70x150x35 offers a compact yet robust envelope, making the NUP314 bearing a versatile choice for various industrial drivetrains. Its 70 mm bore, 150 mm OD, and 35 mm width ensure stable mounting and efficient load distribution.

Cage Material: Two-piece brass cage (ENM designation) for enhanced durability, wear resistance, and smooth operation at high speeds. This brass cage construction is particularly valued by a professional single row cylindrical roller bearing supplier when targeting long service life in continuous running machinery.

Precision & Clearance: JIS standard precision with C3 radial internal clearance for thermal expansion compensation in high-speed or high-temperature environments. The bearing 70x150x35 with C3 clearance reliably maintains proper internal geometry even under fluctuating thermal loads.

Surface Finish: Optimized roller and raceway surfaces to promote hydrodynamic lubrication, reducing friction and extending service life. Combined with the precision of the bearing 70x150x35, this surface treatment ensures consistent performance, a key requirement that every qualified single row cylindrical roller bearing supplier emphasizes in their product documentation.

FAQ

Q1: What are the exact dimensions and structural features of the NUP314 bearing?

A1: The NUP314 bearing has a metric size of bearing 70x150x35 (70 mm bore × 150 mm outer diameter × 35 mm width). It is built as a single row cylindrical roller bearing with an NUP-type design—one integral rib on the inner ring plus a loose flat retaining ring—so it can carry heavy radial loads and locate the shaft axially in both directions. As a professional single row cylindrical roller bearing supplier, HECTO also offers the ENM variant with a two-piece brass cage and C3 clearance for high-speed or high-temperature running.

Q2: Which applications is the bearing 70x150x35 most suitable for?

A2: Because the bearing 70x150x35 combines line-contact rollers with a separable inner/outer ring design, it is widely used in gearboxes, electric motors, industrial reducers, pumps, compressors, machine-tool spindles and construction machinery. The NUP314 bearing version is especially valued when moderate bidirectional axial positioning is required alongside high radial capacity. Buyers usually source it from a single row cylindrical roller bearing supplier that can guarantee IATF16949-level quality control and 100% inspection.

Q3: Why source NUP314 bearing 70x150x35mm from HECTO instead of a trading-only company?

A3: HECTO is a factory-direct single row cylindrical roller bearing supplier with over 20 years of NUP314 manufacturing and export experience, IATF16949 certification, and full product traceability. Every NUP314 bearing we ship is 100% inspected, priced competitively, and delivered on time in more than 99% of cases. For any bearing 70x150x35 order, our team responds quickly to technical questions and provides complete dimension, load (C≈236 kN, C₀≈228 kN) and speed data (reference ~4800 r/min, limiting ~5600 r/min) so engineers can specify with confidence.
