Available in both square and grid patterns, fiberglass grating is widely used due to its low maintenance cost combined with unmatched resilience. Unlike metal gratings, which in certain environments can require extended product life cycle; fiberglass grating is corrosion and rust free, making it more cost effective. Chemical attacks are also not an issue with fiberglass gratings, ensuring its durability. Ideal for the corrosive environment, FRP gives it the complete value for the money.
ZZ，、、，。- Needle Roller Bearings: Needle roller bearings feature cylindrical rollers with a much smaller diameter-to-length ratio compared to cylindrical rollers. This design allows for a higher load-carrying capacity in a compact space, making needle roller bearings suitable for applications with limited radial space.
