Product Description

Linear Motion Sliding Sleeve Bearing introduction :

Agricultural machinery bearing is an important basic component of agricultural machinery equipment. Widely used in agricultural vehicles, tractors, diesel engines, electric machines, rakes, balers, harvesters, threshers and other agricultural machinery. Its accuracy, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the main machine.

Working principle
1.keep the bearing internal high-quality grease and prevent contaminants and water into the bearing. 
2. efficient sealing increases the service life of bearings, but also extends the working life of agricultural machinery. Pedestal ball bearings are mainly used in the field of agricultural machinery harvesting machinery. 
The ball bearing and the bearing housing unit are easy to install and can compensate the misalignment of the shaft in a certain range.

According to the specification standard points:
1: the standard specification (metric size as standard, with straight axis diameter tolerance is usually h7, Asian countries have used)
2: European standard specifications (on the basis of inch size. There is also a metric size, with the straight axis diameter tolerance is commonly g6,) is commonly used in European countries
According to the shape of points:
Type 1: straight (shapes such as cylinders, spring is commonly used in installation, for special occasions requiring small installation size)
Type 2: flange (end or intermediate flange, with installation can use screw to install, general component is circular flange, square and trimming type three)
3: open your mouth (shape, such as straight, appearance has axial slitting, used to need clearance adjustment, large openings and small openings)

According to the performance points:
1: normal (generally use of performance requirements)
Type 2: super (long life and large load performance requirements)

Maintenance for linear bearings :

Metal linear bearing maintenance: lubrication and friction: linear bearing internal injection anticorrosive oil, if use grease lubrication, use kerosene or organic solvent first remove anticorrosive oil, dried to add grease.(it is recommended to use the cohesive markers for N0.2 lithium soap grease.) if the oil lubrication, don't need to remove anticorrosive oil, according to the temperature change can choose ISO viscosity lubricating oil level Shaft lubrication oil pipe in water supply for people, or for oil from the oil hole on the bearing seat.Because of the sealing ring will scrape the lubricating oil, oil lubrication is not applicable to nonporous sealing ring bearing.

Application Scenarios

1, smelters, mines, steel mills rolling machinery and equipment endurance bearings.

2, power plant, gas turbine, motor plant power equipment high requirements bearing. This kind of equipment is mostly continuous operation, bearing force is large, installation and disassembly trouble, inconvenience to replace, so the bearing quality is very stable, wear-resistant and pressure-resistant.

3, printing, packaging machinery, food machinery, special bearings and outer spherical bearings.

4, plastic, chemical fiber machinery, film stretching, special bearings and high temperature bearings.

5, toys, clocks, electronic, audio and video equipment fine bearings.

6, textile, washing, shoe, tobacco machinery selection of bearings. This kind of bearing is small and exquisite, efficient and durable, requiring high speed and minimal noise

7, beer, beverage equipment, medical equipment selection of bearings.

8, crushing, ceramic machinery, fine chemical machinery selection of bearings. The working environment of this kind of equipment is poor, and there are many water mist, moisture, dust, acid and alkali effects, requiring strong bearing sealing, sufficient and reasonable grease, and it is best to add grease in time.
