A spline roller is a handy tool used in the installation and repair of window screens and screen doors. It is specifically designed to assist in the process of inserting Screen Spline into the frame's groove, ensuring a secure and tight fit. The roller features a cylindrical wheel attached to a handle, allowing for smooth and controlled pressure as it rolls along the spline, pushing it into the groove. This tool is essential for both DIY enthusiasts and professionals, as it simplifies the task of installing or replacing screen spline, resulting in properly fitted screens that provide effective protection and ventilation.

The single-row four-point touch ball slewing bearing consists of two races; compact layout, light weight, four-point touch of steel ball and circular raceway; can accept axial force, radial force and tilting torque together. Reverse type Conveyor, welding machine, small and medium-sized cranes and excavators can be used. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Single row insert roller slewing bearing single row insert roller type reverse bearing; composed of two races; compact layout, light weight, high precision; installation clearance. Garden 沧熬 蟾撸 蟾撸 鲋 1:1 interpenetration Can be used together to accept axial forces, large radial forces and tipping moments. It is widely used in lifting and transportation, construction machinery and military products.
The three-row combined roller slewing bearing has three rows of roller-type reverse bearing with three races, which are separated by upper and lower and radial raceways; so that the load of each row of rollers can be determined locally. Various loads can be accepted together. It is one of the four types of products with the largest bearing capacity; the radial radial dimension is large; the layout is strong; uniquely suitable for heavy machinery with large diameter; such as bucket wheel excavator, wheeled crane, boat crane , steel running table and large tonnage steam cranes and other machinery.
Double-row angle touch ball slewing bearing double volleyball type reverse bearing has three races; steel ball and block can be directly discharged into the upper and lower raceways; according to the force condition; the upper and lower rows of steel balls with different diameters are organized.
This open installation is very convenient; the upper and lower circular raceways have a bearing angle of 90°; they can accept large axial forces and tilting moments; when the radial force is greater than 0.1 times the axial force of the raceways It must be uniquely depicted. The double volleyball type reversing bearing has large axial and radial dimensions and is consolidated. It is uniquely applicable to loading and unloading machinery such as tower cranes and truck cranes with medium and large diameters.
