The linear ball bearing (also called ball bushing or shaft guiding) consists of a polymeric cage with raceway segments made of hardened steel to guide the ball sets within the complete system. Recirculating balls provide unlimited stroke at low friction movement.
Linear motion is the most basic of all motion. Linear Ball Bearings provide linear movement in one direction. Liner Bearings,Liner Guide Bearing,Ball Bearing Linear Stages,Linear Bearings And Guides Ningbo Ritbearing Imp & Exp Co.,Ltd. , https://www.nbbearing.de
Application range:
1. Single or multiple pipelines for fire blocking 2. Temporary or permanent plugging of cable bundles and cable tray crossings 3. Temporary or permanent plugging of flammable pipelines 4. Metal piping with or without thermal insulation Temporary or permanent plugging installation instructions:
Opening:
1, clean the opening;
2. If it is used for the opening of non-transit material (temporary fire blocking), it means that the long side of the fire blocking module is flush with the substrate, and the flat and stable structure is built in the opening;
3, if it is used to open the hole through the object, you can use a knife cut fire blocking module to meet the size of the crossing;
4. Keep the long side direction of the fire blocking module flush with the substrate, and build a smooth and stable structure in the opening;
5. Seal the cable gap with an intumescent sealant and the gap between the fire blocking module and the cable;
6. If necessary, install identification stickers on the conspicuous position beside the fireproof plugging part to identify it as a mark for later maintenance;
Again through the installation:
1, in the area of ​​change, remove or remove the fire resistance module;
2. Install traverses, reconstruct fire-resistance module, and seal with an intumescent fire sealant or a flexible organic plugging material;
3. When passing through a single cable again, you can directly pass through the joint between the fire-resistant modules, or use a sharp metal pipe or hose to drill the fire-resistant module through a hole with a smaller diameter, and use it to seal with an intumescent sealant. .
A roller bearing, carries a load by placing rolling balls or rollers between two bearing rings called races. These bearings are comprised of an outer ring and several rows of balls retained by cages. Roller Bearings are manufactured in two styles: ball slides and roller slides.
The fire-retardant module completely solves the problems of fireproof pillows, fire-proof packages, moisture-proof, corrosion-resistant, rat-biting, code collapse, and short expiration date. The flame-retardant module expands in response to fire, and the released gas is non-toxic, harmless, environmentally friendly, non-polluting and halogen-free. The overall product is composed of a variety of organic substances. The product is naturally engaged and does not require the use of toxic glue such as formaldehyde.
