Cross Tapered Roller Bearing Premium Quality Guaranteed
With the design of 90 vertical cross roller structure, a single bearing can bear great axial force, radial force and tilting moment at the same time. It is specially designed for low-speed rotating scenes such as turntables and agricultural machinery that do not require micron-level precision but require high rigidity and long-term reliability. It can effectively replace the traditional combination of two sets of bearings and save installation space，support for bulk purchases.
Cross Tapered Roller Bearing Important parameters：
Cross Tapered Roller Bearing characteristics
Integrated three-way carrying capacity
A 1:1 cross roller arrangement design is adopted, and the rollers are vertically crossed in a 90 ° V-shaped raceway. the load carrying capacity is 30%-50% higher than that of ball type slewing bearing, and can bear axial load, radial load and tilting moment of up to thousands of nm at the same time, ensuring the absolute stability of the equipment under eccentric load conditions.
Rigidity of structure to prevent swaying of turntable
The clearance between the roller and the raceway is eliminated by the preload design (adjusted according to the application scenario) and the bearing rigidity is improved. When agricultural machinery or lifting equipment passes through uneven ground, it can effectively resist shock and vibration, prevent the turntable from shaking, and ensure long-term operation without loosening.
Industrial grade durable material
The ferrule is made of high quality 42CrMo material, the raceway is treated by surface induction quenching, the hardness reaches 55-60 HRC, and the effective hardening layer depth is more than 3mm. In dusty, sediment and other harsh conditions, raceway wear resistance increased by 30%, the design life of up to 5 years.
Compact space design
The unique single-row structure design enables it to replace the combination of “radial bearing + thrust bearing. It greatly reduces the structural weight and processing cost of the host, and is especially suitable for rotating workbenches with limited installation space.
Sealing performance reduces maintenance costs
Equipped with double-lip NBR (nitrile rubber) oil-resistant sealing strip, close to the bearing end face. After testing, it can effectively block 95% of external dust and moisture intrusion, while preventing internal grease leakage, significantly reducing the frequency of subsequent maintenance and lubrication costs.
Flexible gear customization
Three structural options are available: external teeth, internal teeth and no teeth. Gear machining accuracy grade can reach ISO 8-10, and the wear resistance of the tooth surface is enhanced after quenching treatment. When used with a pinion, the transmission efficiency is as high as 92%, meeting the transmission requirements of low speed and high torque.

Rotating mechanisms for harvesters, sprinklers and tractor auxiliaries. The product can resist muddy water erosion and strong vibration in field operations, and meet the core requirements of agricultural machinery for “durable leather and simple maintenance” of parts, without the need for laboratory-level rotation accuracy.
Industrial Rotary Table and Displacement Machine Manufacturer
Suitable for welding displacement machine, filling machine turntable and other automation equipment. The excellent resistance to tipping moment provided by the cross-roller structure ensures that the turntable can still maintain smooth rotation when carrying eccentric workpieces (such as large weldments), and the cost is much lower than that of precision machine tool bearings.
Lifting and transportation equipment R & D personnel
Slewing base designers for truck cranes, aerial vehicles and small excavators. The high load-to-density ratio of the bearing allows 360-degree full rotation in limited chassis space, and the forged steel material can withstand sudden impact loads when lifting heavy objects.
Purchasers of environmental protection and water treatment equipment
It is suitable for low-speed continuous operation equipment such as mud scraper and sewage treatment rotating grid. The main value of the product’s anti-corrosion potential and long-term sealing performance, can be in a humid, high humidity environment to maintain 24 hours of continuous operation without stuck.
Cross Tapered Roller Bearing life and after-sales service
Expected service life:
The design life of this product is 5-7 years under normal rated load and standard maintenance (grease replenishment every 50-60 hours of operation). For agricultural machinery with high dust or high impact, it is recommended to shorten the maintenance cycle to ensure stable operation of at least 3000-5000 working hours.
Pre-sales and after-sales service:
We provide the whole process service from selection calculation to installation guidance. Our professional engineers have rich experience in slewing bearings, and the seller has rich experience in export business, and can provide the best suggestions according to your special requirements. Any feedback on product quality will be replied within 24 hours, and if there is a quality problem, it will be sent again for compensation.
Cross Tapered Roller Bearing Raw Material/Material Description
Inner and outer rings: strict selection of 42CrMo high-quality alloy structural steel. Through quenching and tempering treatment , ensure that the core has sufficient toughness to resist impact and avoid fracture under high load.
Rolling element: GCr15 bearing steel, after precision grinding and heat treatment, uniform hardness, excellent wear resistance, is the core component to ensure the accuracy of the bearing.
Spacers: standard high-strength nylonisolation block, with self-lubricating performance, can effectively reduce friction noise.

Our factory
A: For standard models, the lead time is 15-30 days. Custom products may take longer depending on specifications.
A: Every product is tested for dimensions, hardness, gear and raceway quenching quality, and operational performance before delivery.
A: Yes. As a slewing bearing, the inner and outer rings of the product are prefabricated with standard mounting holes, which are convenient to fix directly with bolts. At the same time, we provide three forms of toothless, internal and external teeth, which can be selected according to your driving mode.
A: Although this series does not require ultra-high precision, in order to prevent the deformation of the raceway from causing jamming, the flatness error of the mounting seat should be controlled within 0.1 mm-0 mm (depending on the bearing diameter), and the flatness of the mounting surface should be kept clean and smooth, and controlled according to the table provided by our company.
A: For agricultural machinery and ordinary turntable applications, we usually provide standard clearance to adapt to temperature changes and installation errors to prevent stuck. If you use it for positioning turntables with high accuracy requirements, we can customize micro-preload or zero-clearance products.
A: The slewing bearing has been filled with a small amount of EP2 grease in the raceway before leaving the factory. Be sure to fill with grease before installation, and then refill every 50-60 hours of work (except for harsh environments). In addition, in order to ensure that the grease is evenly distributed, the slewing bearing must be rotated smoothly during oil injection.
