Product Description: Double-deep racking, also known as double-deep pallet racking or double-row racking, is a high-density storage solution designed to optimize warehouse storage capacity. This racking system is particularly suitable for storing large quantities of the same type of goods, especially in scenarios where the frequency of inbound and outbound operations is not extremely high. The following are the main features of double-deep racking:Main Features:1. Double-pallet design: Unlike traditional single-pallet racking, double-deep racking provides two storage positions in each storage aisle, meaning goods can be accessed from both sides of the rack.2. High space utilization: By placing two rows of goods in each aisle, double-deep racking significantly improves warehouse space utilization.3. Flexible access: Goods can be accessed from either side of the rack, providing greater flexibility for warehouse logistics.4. Suitable for storing large quantities of identical goods: Due to its design characteristics, double-deep racking is particularly suitable for storing large quantities of the same type of goods, such as food and beverages, daily necessities, etc.Applicable Scenarios:Double-deep racking is suitable for various warehouse environments, especially in the following situations:1. Warehouses storing large quantities of identical goods.2. Scenarios where warehouse space is limited and needs to be utilized efficiently.3. Businesses where the frequency of goods movement is not high, and the requirement for access speed is not extremely critical. more>

Product Description: Inner diameter range: 10-85mmProduct grade: P4Vibration level: V3Bearing material: Bearing steelMinimum order quantity: 100 setsDeep groove ball bearings have a very wide range of applications. They are suitable for high and ultra-high speeds, accommodate radial and axial loads in both directions, and require almost no maintenance. Deep groove ball bearings are one of the most widely used bearing types. Oukai Bearings offers deep groove ball bearings in various designs, variants, and sizes.Deep groove ball bearings come in both single-row and double-row types. The structure of deep groove ball bearings also includes sealed and open types. Open type means the bearing does not have a sealing structure. Sealed deep groove ball bearings are divided into dust-proof seals and oil-proof seals. The dust-proof seal cover is made of stamped steel plate, which simply prevents dust from entering the bearing raceway. The oil-proof type is a contact oil seal that effectively prevents the grease inside the bearing from leaking.Deep groove ball bearings primarily withstand radial loads but can also simultaneously handle radial and axial loads. When they only bear radial loads, the contact angle is zero. When deep groove ball bearings have a large radial clearance, they exhibit the performance of angular contact bearings and can withstand significant axial loads. Deep groove ball bearings have a very low friction coefficient and a high limiting speed. more>
