Different materials outdoor furniture hardware maintenance
Outdoor furniture is different from ordinary indoor furniture. Because outdoor furniture is placed outdoors for a long time, it must have sun protection, waterproof and corrosion resistance. Although outdoor furniture has these characteristics, daily cleaning and maintenance are still indispensable. Because it is placed outdoors, the usual dust accumulation time will be agglomerated on the furniture, and the water will cause some areas to be wet for a long time, which will cause corrosion of furniture, especially furniture hardware. For example, stainless steel legs, cast iron legs, aluminum alloy legs, etc. in an outdoor table. Special attention should be paid to the metal parts of outdoor furniture.
Outdoor furniture is generally treated with special waterproof, sunscreen, anti-corrosion technology, and it will be much simpler to clean than ordinary furniture.
Aluminum alloy: If there is stain on the surface, wipe it with water. Do not use concentrated acid or alkaline cleaner.
Teslinbu: Wash directly with cloth and clean water.
Wooden table and chair: Wipe with a rag, do not scratch with a hard object, so as not to damage the waterproof layer on the surface.
PE rattan: PE rattan furniture can be cleaned with a soft brush, rag or vacuum cleaner. It should be protected from collisions and sharp edges or hard objects. PE vines can be protected from moisture, aging, insects and infrared rays, so you don't have to worry too much about maintenance.
Furniture materials: Because the material is soft, avoid collision with hard objects. Do not use metal brushes to prevent bumps and scratches. Ordinary detergents can be used as the cleaning agent. If cracks occur, they can be repaired by hot melt.
Furniture metal fittings: Prevents the surface of metal fittings from colliding and scratching when moving. Damage to the surface of metal fittings can affect their corrosion resistance. Do not stand on the folding furniture to avoid deformation of the folding part and affect the use. Simply scrub with warm soapy water and do not use strong acid or alkaline cleaner to avoid rusting the surface protection layer.
Tempered glass: Although tempered glass is harder than ordinary glass, it should also avoid collision with hard objects, especially at the corners of glass to prevent breakage and chipping due to collision. Do not use corrosive detergents to clean the glass surface, and do not use hard scrapers or metal cleaning brushes to clean the surface to prevent surface damage due to hard wiping.

Spherical Roller Bearings are most suitable option for applications that need shock resistant components yet this is not the only quality these Bearings have. These Bearings can handle heavy loads because of their rings` alignment. Due to the curved outer ring, Spherical Bearings come with self aligning capabilities that make it possible to absorb shocks and also enable the apparatus to carry high axial and radial load even in harsh environment with lot of vibration. Even with this rugged working environment, Roller Bearings tend to have high precision.
DESIGN
Spherical Bearings have two rows of rollers that are separated by a cage or rib that could be sealed or unsealed depending on the specific model and application, external raceway and dual raceways in inner ring to support rotating shaft. Amazingly the quality and alignment of raceways, cages and rings define the overall performance and quality of the product. Asymmetrical rollers increase performance and precision while symmetrical rollers offer better load distribution, lesser vibration that ultimately leads to durability.
MATERIAL
These Bearings are manufactured with several kind of material based on the application and working environment. Chrome steel is one of the most popular materials used in production of these Bearings because of its durability yet sheet steel, polyamide and brass are also used for some applications. One of the most important parts of Spherical Bearings is the cage that holds bearings at their place. That cage is usually manufactured with pressed steel or brass because both of these materials offer strength as well as temperature resistance.
These Bearings tend to have seals in order to prevent contaminants like dirt, liquid, debris as well as harsh temperature. This type of these bearing doesn`t even need lubrication if they do not exceed 50% of their maximum allowed RPM.
APPLICATIONS
Spherical Bearings are essential part of heavy machines like gearboxes, turbines, mechanical fans, constructions equipment, mining equipment and drilling equipment. Roller Bearings are available in multiple standard sizes and dimension yet they are also made with custom sizes and specifications.

MODELS AND VARIATIONS
Usually these Bearings come in two different types that have totally different design, structure, specifications and applications.
Single Row Spherical Roller Bearings
These are also known as Barrel Bearings because of their design and they are widely used where only low radial load carrying capacity is required. Other than the load capacity difference, Single Row these Bearings is quite similar to their counterpart in terms of performance and durability.
Double Row Spherical Roller Bearings
These are used where high radial load carrying capacity if required and that make them an essential part of almost all heavy duty machinery out there. The design difference between these two is obvious; Double Row Roller Bearings come with central flanges that optimize the overall performance of the apparatus.
