A slew drive is a gearbox mechanism that integrates a slewing ring bearing with a worm gear system to enable rotational movement under load. In solar tracking systems, slew drives play a crucial role by precisely orienting photovoltaic (PV) or concentrating solar power (CSP) panels toward the sun throughout the day, thereby maximizing energy generation.
Unlike fixed-mount solar panels, solar trackers equipped with slew drives can boost energy yields by 20–45%, depending on location and configuration. Selecting the correct slew drive for your tracking application is essential for performance, durability, and return on investment.
Types of Slew Drives for Solar Tracking
There are two common categories of slew drives used in solar applications:
Single-Axis Slew Drives
Function: Rotates panels from east to west.
Ideal For: Most ground-mount PV arrays and utility-scale projects.
LDB Models: SE Series, S Series
Dual-Axis Slew Drives
Function: Enables both horizontal and vertical movement.
Ideal For: CSP systems, concentrated PV, off-grid trackers, and regions with variable sunlight angles.
LDB Models: VE Series, HSE Series, HSE-2 Series
Key Selection Criteria
Torque Requirements
Slew drives must withstand wind loads and panel weight. Calculate holding torque and tracking torque under worst-case wind scenarios.
LDB provides torque charts for all models. For example, the HSE Series supports up to 25,000 Nm.
Rotation Range and Precision
Most solar applications require up to ±90° of rotation. Look for worm gears with low backlash for improved tracking accuracy.
Dual-worm configurations (like SDE-PDE Series) can enhance torque and positioning precision.
Self-Locking Capability
Worm gear-based slew drives have a natural self-locking mechanism, preventing back-driving from wind forces—an important safety and energy-saving feature.
IP Rating and Weather Resistance
Outdoor solar trackers require drives rated at least IP66 to protect against dust, rain, and UV exposure.

Introduction: Why Sealing and IP Ratings Matter for Slew Drives
Slew drives are essential rotary motion control components widely used in solar trackers, cranes, wind turbines, and industrial automation. These systems often operate in challenging environments—exposed to dust, water, sand, or corrosive agents. A key factor determining their longevity and reliability is the integrity of their sealing structure and the corresponding IP (Ingress Protection) rating.
This article provides a comprehensive guide to sealing technologies, IP rating standards, and practical considerations when selecting a slew drive for use in harsh or outdoor environments. It also highlights supplier and manufacturer guidelines, pricing implications, and how LDB Bearing delivers sealed, durable slew drive solutions built for real-world conditions.
Understanding IP Ratings and Their Importance
IP rating stands for Ingress Protection, a globally recognized standard defined by IEC 60529. It classifies the degree of protection provided by an enclosure against:
Solids (first digit): Dust, sand, and debris
Liquids (second digit): Water, rain, and chemical splashes
Common IP Ratings in Slew Drives:
IP54: Protection against limited dust ingress and splashing water
IP65: Complete dust protection and water jets from any direction
IP66: Dust-tight and protected against strong water jets
IP67: Dust-tight and protected against immersion up to 1 meter
Higher IP ratings directly contribute to longer component life, less downtime, and better performance in exposed environments.
Types of Sealing Structures in Slew Drives
Radial Shaft Seals (Lip Seals)
Most commonly used
Made from rubber, nitrile, or fluoropolymer
Designed to retain lubrication and exclude contaminants
Labyrinth Seals
Non-contact design
Multiple paths restrict dust and moisture ingress
Preferred in high-speed or low-maintenance applications
O-Ring and Gasket Seals
Used in the housing covers and interfaces
Provide static sealing under bolt compression
Double Sealing Structures
Combine lip seals and O-rings
Provide redundancy in extreme environments (e.g., offshore wind farms, desert solar farms)
Factors Influencing Seal and IP Selection
Environmental Conditions:
Dusty industrial areas: IP65 or higher with double lip seals
Offshore and marine zones: IP66 or IP67 with corrosion-resistant seals
High humidity or rainy climates: Prioritize water-resistant materials (e.g., FKM, HNBR)
Motion and Load Cycles:
High cycle applications require seals that maintain flexibility over millions of movements
Maintenance Access:
Remote locations benefit from sealed-for-life designs with low-maintenance sealing systems
Cost, Supplier, and Manufacturer Considerations
Price Implications:
Higher IP ratings typically require better materials and precision machining
However, the added cost often offsets long-term repair or replacement expenses
Supplier Evaluation:
Ensure the supplier provides documented IP ratings and material specs
Prefer vendors with field-tested solutions and industry-specific certifications (e.g., CE, RoHS)

An SE Series Slew Drive is a compact and sealed rotational actuator that integrates a slewing bearing with a worm gear mechanism, designed to deliver torque, rotational stability, and self-locking capability. SE series drives are ideal for applications where slow, controlled rotation is required, such as in solar panel tracking, lifting systems, or satellite positioning.
The hallmark of the SE series is its enclosed, weatherproof construction and bi-directional motion capability. It is one of the most commonly used types of slew drives in solar energy systems worldwide.
Core Technical Features
Self-Locking Worm Gear Mechanism SE slew drives use a worm-and-wheel setup where the worm gear provides inherent self-locking properties, which helps panels or equipment hold position against external forces like wind.
Enclosed Housing (IP66 and Above) These units are designed to operate in harsh outdoor conditions, with excellent protection from dust, rain, and sand. Higher protection levels are available for offshore or desert deployments.
Bi-Directional Mounting The SE series supports horizontal and vertical mounting, offering installation flexibility on poles, flat platforms, or mobile systems.
Compatibility with Motor Systems SE slew drives can be powered by hydraulic or electric motors and offer precise control over speed and torque through motor configuration.
