Needle roller bearings play a crucial role in ensuring the smooth and efficient operation of various components within a motorcycle. From the wheels to the engine, bearings are integral to reducing friction and allowing parts to move freely.
Modern consumers are increasingly demanding whether home appliances are comfortable, safe, energy-saving, and environmentally friendly or not. Using durable, high-precision, low-vibration, high-quality bearings not only can reduce the energy consumption of mechanical operation but also save you more energy and cost on maintenance and replacement parts in the future to be more energy-saving and environmental protection.
deep groove ball bearings are commonly used in wheel hubs, transmission systems, and electric power steering units to ensure smooth and reliable vehicle performance.

Key Features of Needle Roller Bearings
Light Weight
High Load Capacity
Limited Space

Needle roller bearings, also known as needle bearings, are a type of rolling bearing characterized by their slender and elongated needle-shaped rollers. Compared to ball bearings, needle roller bearings have a smaller cross-sectional area and volume but possess higher load-carrying capacity. This makes needle roller bearings excel in applications with limited space, particularly in cases of radial space constraints.
It is made with relatively heavy but thin outer ring, made from hardened and precision ground materials, thus provides the smallest section height.
The TA series, also known as drawn cup needle roller bearings, are characterized by their thin-walled outer rings drawn from high-quality steel. These bearings are compact and offer excellent performance in applications where radial space is limited.
Drawn cup needle roller bearing(TA Series) is one of the needle roller bearings. It composed of thin walled punched outer ring, retainer and a group of needle rollers. It is usually formed with thin steel plate through precision punching with very sectional height and big load capacity, so it is suitable for the needed of the low cost and mass produced.

Similar to the TA series, HK series bearings also feature a drawn cup design. It composed of thin walled punched outer ring, retainer and a group of needle rollers. It is usually formed with thin steel plate through precision punching with very sectional height and big load capacity, so it is suitable for the needed of the low cost and mass produced.
Drawn cup needle roller bearing is used between the needle bearings and the bearing cage, and no axial fixture device is required. Even under the condition of high speed and heavy load, the original function of the bearing can be fully maintained, and not to be easily damaged. Due to the high storage volume of grease, the drawn cup needle roller bearing possibly without lubricating for a long time.
The HF series, or needle roller freewheel bearings, allow rotation in one direction while blocking reverse motion. They are crucial for applications like conveyor systems, indexing mechanisms, and packaging equipment that require backstopping or overrunning functions. HF bearings provide precise motion control and prevent unintended movement in mechanical systems.
The HF Series one-way drawn cup needle roller clutch bearing consists of a thin-walled alloy steel outer ring and a plastic retainer. The inner surface of the outer ring securely holds the needles. With its slim design, the clutch offers low torque. Each needle is supported by an independent spring, enabling high switching frequency and precision.
NK series bearings, designed without an inner ring, provide a compact and lightweight solution for applications where the shaft cannot serve as a raceway. Ideal for high-speed operations, they are commonly used in automotive components like crankshafts and cam followers, where space and weight are key considerations.
Entity bushed needle roller bearing(NK Series) is a kind of high capacity bearing with small sectional height. It can operate very flexibly even with the light alloy bearing seat due to its high hard outer ring. There are two series: metric and inch series. Both of which are structured with retainer, full needle and sealing types.
Besides, the entity divides bush needle roller bearings into two kinds: those with an inner ring and those without a ring. The design team uses the center shaft as a rolling body tray for those without an inner ring, making its size even smaller.
Solid drawn cup needle roller bearings are a type of bearing with a small cross-sectional height and high load-carrying capacity. Due to the high hardness of the outer ring, it can be applied to even lightweight alloy bearing seats.
These bearings provide products in both metric and imperial series, with three types of structures in each series: a cage type, a full-needle type, and a sealed type.
In addition, solid drawn cup needle roller bearings are divided into two types: NA with an inner ring and RNA without an inner ring, with the latter using the shaft as the rolling surface to reduce its size.
Solid drawn cup needle roller bearings have a small cross-sectional height and high load capacity. Their hardened outer ring allows use with lightweight alloy bearing seats. These bearings come in two types: NA (with an inner ring) and RNA (without an inner ring). The RNA type uses the shaft as the rolling surface, making it more compact.
RNA series bearings, similar to NK series but without an inner ring, are ideal for applications with limited radial space. They are commonly found in textile machinery, printing presses, and packaging equipment, offering excellent radial load-carrying capacity and compact design. RNA bearings ensure smooth and efficient operation in confined spaces.
The AXK series thrust needle bearing consists of a tray ring gasket combined with a retainer holding needle roller bearings. The design allows for many rolling elements to be held in place, with minimal variation among them. These bearings are capable of supporting axial loads and are ideal for applications requiring high rigidity and minimal axial space.
AXK series bearings feature needle rollers and a cage assembly, offering excellent axial load capacity and stiffness. They are essential in applications with high axial loads, such as automotive transmissions, agricultural machinery, and heavy industrial equipment. AXK bearings provide reliable and precise axial motion control, ensuring smooth operation in mechanical systems.
KT radial needle roller and cage assemblies bearing is a kind of independent bearing unit with high load capacity and rigidity especially applicable for the tray of shaft and seat holes with the unit which is limited in radical dimension. Each needle have excellent operative characteristic due to each needle exactly guided and kept by the retainer.
KT series bearings, comprising cage and needle roller assemblies, are lightweight and compact, making them suitable for high-speed operations. They are commonly used in automotive engines, compressors, and industrial pumps, where their ability to handle both radial and axial loads is crucial for efficient performance. KT bearings ensure optimal functionality in demanding applications.
